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.
It's very simple,
just run the following commands
sudo a2enmod ssl
sudo service apache2 restart
sudo a2ensite default-ssl.conf
That's it, you are done.
If you want to force SSL (to use https always), edit the file:
sudo nano /etc/apache2/sites-available/000-default.conf
and add this one line
<VirtualHost *:80>
. . .
Redirect "/" "https://your_domain_or_IP/"
. . .
</VirtualHost>
then restart again
sudo service apache2 restart
When the above solution doesn’t work try this:
<IfModule mod_security.c>
SecRuleEngine Off
SecFilterInheritance Off
SecFilterEngine Off
SecFilterScanPOST Off
SecRuleRemoveById 300015 3000016 3000017
</IfModule>
I struggled to understand the proxy settings for websockets for https therefore let me put clarity here what i realized.
First you need to enable proxy
and proxy_wstunnel
apache modules and the apache configuration file will look like this.
<IfModule mod_ssl.c>
<VirtualHost _default_:443>
ServerName www.example.com
ServerAdmin webmaster@localhost
DocumentRoot /var/www/your_project_public_folder
SSLEngine on
SSLCertificateFile /etc/ssl/certs/path_to_your_ssl_certificate
SSLCertificateKeyFile /etc/ssl/private/path_to_your_ssl_key
<Directory /var/www/your_project_public_folder>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
php_flag display_errors On
</Directory>
ProxyRequests Off
ProxyPass /wss/ ws://example.com:port_no
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
</IfModule>
in your frontend application use the url "wss://example.com/wss/"
this is very important mostly if you are stuck with websockets you might be making mistake in the front end url. You probably putting url wrongly like below.
wss://example.com:8080/wss/ -> port no should not be mentioned
ws://example.com/wss/ -> url should start with wss only.
wss://example.com/wss -> url should end with / -> most important
also interesting part is the last /wss/
is same as proxypass
value if you writing proxypass /ws/
then in the front end you should write /ws/
in the end of url.
Use $_SERVER['HTTPS']
to tell if it is SSL, and redirect to the right place if not.
And remember, the page that displays the form does not need to be fed via HTTPS, it's the post back URL that needs it most.
Edit: yes, as is pointed out below, it's best to have the entire process in HTTPS. It's much more reassuring - I was pointing out that the post is the most critical part. Also, you need to take care that any cookies are set to be secure, so they will only be sent via SSL. The mod_rewrite solution is also very nifty, I've used it to secure a lot of applications on my own website.
This post is intended to rescue the people who are suffering from *not being able to properly setup Apache2 for Perl on Ubuntu. (The system configurations specific to your Linux machine will be mentioned within square brackets, like [this]).
Possible outcome of an improperly setup Apache 2:

Now add, your Perl script as test.pl in the place where you mentioned before in step 3 as [path-where-you-want-your-.pl-and-.cgi-files].
Give permissions to the .pl
file using chmod
and then, type the webaddress/cgi-bin/test.pl
in the address bar of the browser, there you go, you got it.
(Now, many of the things would have been redundant in this post. Kindly ignore it.)
if you can get the proper response in your localhost and getting this error kind of error and if you are using nginx
.
Go to Server and open nginx.conf with :
nano etc/nginx/nginx.conf
Add following line in http block :
proxy_buffering off;
Save and exit the file
This solved my issue
When we apply local url, ErrorDocument directive expect the full path from DocumentRoot. There fore,
ErrorDocument 404 /yourfoldernames/errors/404.html
You can place an empty file called index.html
into each directory that you don't want listed. This has several advantages:
.htaccess
files, this can lead to lots of "Error 500 - internal server error" messages for your users!). Theoretically, the autoindexing might be triggered by a different file (this is controlled by the DirectoryIndex
option), but I have yet to encounter this in the real world.
I had to disable OSX's built-in Apache server (XAMPP support thread):
sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist
This allowed XAMPP to start on 80, while POW runs on 20559.
What had failed: I reconfigured /etc/apache2/httpd.conf
to listen on an alternate port and rebooted OSX. No luck.
If you have apache running, put your file in server folder for html files and then call it from web-browser (Like http://localhost/myfile.php ).
In Apache 2.4, there's a new stock module called mod_ratelimit. For emulating modem speeds, you can use mod_dialup. Though I don't see why you just couldn't use mod_ratelimit for everything.
There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).
Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.
Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.
You can also put in a new virtual Host entry in the
c:\xampp\apache\conf\httpd-vhosts.conf
like:
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "C:/xampp/htdocs/myproject/web"
ServerName localhost
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common
</VirtualHost>
With my centos 6.7 installation, not only did I have the problem starting httpd with root but also with xauth (getting /usr/bin/xauth: timeout in locking authority file /.Xauthority
with underlying permission denied errors)
# setenforce 0
Fixed both issues.
Have you changed the permissions on the individual files as well as just the directory?
chmod -R 777 /home/user/xxx
Got the solution and it's working fine. Set the environment variables as:
CATALINA_HOME=C:\Program Files\Java\apache-tomcat-7.0.59\apache-tomcat-7.0.59
(path where your Apache Tomcat is)JAVA_HOME=C:\Program Files\Java\jdk1.8.0_25;
(path where your JDK is)JRE_Home=C:\Program Files\Java\jre1.8.0_25;
(path where your JRE is)CLASSPATH=%JAVA_HOME%\bin;%JRE_HOME%\bin;%CATALINA_HOME%\lib
It's a simple problem. When you are running from terminal, you are running the php file from terminal as a privileged user. When you go to the php from your web browser, the php script is being run as the web server user which does not have permissions to execute files in your home directory. In Ubuntu, the www-data user is the apache web server user. If you're on ubuntu you would have to do the following: chown yourusername:www-data /home/testuser/testscript chmod g+x /home/testuser/testscript
what the above does is transfers user ownership of the file to you, and gives the webserver group ownership of it. the next command gives the group executable permission to the file. Now the next time you go ahead and do it from the browser, it should work.

I had a messed up virtual host config. Remember you need one virtual host without SSL for port 80, and another one with SSL for port 443. You cannot have both in one virtual host, as the webmin-generated config tried to do.
I had the same issue and finally solved it. My mistake was that I tried to change /etc/php5/cli/php.ini, but then I found another php.ini here: /etc/php5/apache2/php.ini, changed display_errors = On, restarted the web-server and it worked!
May be it would be helpful for someone absent-minded like me.
Load testing your API by using just ab is not enough. However, I think it's a great tool to give you a basic idea how your site is performant.
If you want to use the ab command in to test multiple API endpoints, with different data, all at the same time in background, you need to use "nohup" command. It runs any command even when you close the terminal.
I wrote a simple script that automates the whole process, feel free to use it: http://blog.ikvasnica.com/entry/load-test-multiple-api-endpoints-concurrently-use-this-simple-shell-script

It looks like there are many options. The answer depends on your Windows installation. Here is my experience when having the same problem in a Windows 10 fresh install and fix the issue with the following step:
Listen 80
Listen 443
to Listen 441
Note: I'm using XAMPP version 5.6.15 and XAMPP Control Panel version 3.2.2.
In my case I got the error simply because I had changed the Listen 80 to listen 443 in the file
/etc/httpd/conf/httpd.conf
Since I had installed mod_ssl
using the yum commands
yum -y install mod_ssl
there was a duplicate listen 443 directive in the file ssl.conf
created during mod_ssl
installation.
You can verify this if you have duplicate listen 80 or 443 by running the below command in linux centos (My linux)
grep '443' /etc/httpd/conf.d/*
below is sample output
/etc/httpd/conf.d/ssl.conf:Listen 443 https
/etc/httpd/conf.d/ssl.conf:<VirtualHost _default_:443>
/etc/httpd/conf.d/ssl.conf:#ServerName www.example.com:443
Simply reverting the listen 443 in httd.conf to listen 80 fixed my issue.

You can check your network and sharing center.

First, read this: https://httpd.apache.org/docs/current/howto/htaccess.html#when
Then read my post here: https://stackoverflow.com/a/59868481/10664600
sudo vim /etc/httpd/conf/httpd.conf
This is a quite confusing way of using Apache configuration directives.
Technically, the first bit is equivalent to
Allow From All
This is because Order Deny,Allow
makes the Deny directive evaluated before the Allow Directives.
In this case, Deny and Allow conflict with each other, but Allow, being the last evaluated will match any user, and access will be granted.
Now, just to make things clear, this kind of configuration is BAD and should be avoided at all cost, because it borders undefined behaviour.
The Limit sections define which HTTP methods have access to the directory containing the .htaccess file.
Here, GET and POST methods are allowed access, and PUT and DELETE methods are denied access. Here's a link explaining what the various HTTP methods are: http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html
However, it's more than often useless to use these limitations as long as you don't have custom CGI scripts or Apache modules that directly handle the non-standard methods (PUT and DELETE), since by default, Apache does not handle them at all.
It must also be noted that a few other methods exist that can also be handled by Limit, namely CONNECT, OPTIONS, PATCH, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE, LOCK, and UNLOCK.
The last bit is also most certainly useless, since any correctly configured Apache installation contains the following piece of configuration (for Apache 2.2 and earlier):
#
# The following lines prevent .htaccess and .htpasswd files from being
# viewed by Web clients.
#
<Files ~ "^\.ht">
Order allow,deny
Deny from all
Satisfy all
</Files>
which forbids access to any file beginning by ".ht".
The equivalent Apache 2.4 configuration should look like:
<Files ~ "^\.ht">
Require all denied
</Files>
In my case, I stopped my docker hive container and run it again and finally, it worked. Hope it will be useful for someone.
Note: This might be caused because there might be an instance running in the background so stopping the container will stop all background instances.
Write the root logger as below for logging on both console and FILE
log4j.rootLogger=ERROR,console,FILE
And write the respective definitions like Target, Layout, and ConversionPattern (MaxFileSize for file etc).
You can also set DirectoryIndex in apache's httpd.conf file.
CentOS keeps this file in /etc/httpd/conf/httpd.conf
Debian: /etc/apache2/apache2.conf
Open the file in your text editor and find the line starting with DirectoryIndex
To load landing.html as a default (but index.html if that's not found) change this line to read:
DirectoryIndex landing.html index.html
Attempt 2 was close to perfect. Just modify it slightly:
RewriteEngine On
RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
In case you need to run IIS on port 80/443 but on different IP address, you may use netsh http add iplisten xxx.xxx.xxx.xxx
as described here:
https://support.microsoft.com/en-us/help/954874/iis-binds-to-all-ip-addresses-on-a-server-when-you-install-iis-7-0-on
More details about netsh http add iplisten

Took some tooling around but this is what I ended up with.
Generated and installed a certificate on IIS7. Exported as PFX from IIS
Convert to pkcs12
openssl pkcs12 -in certificate.pfx -out certificate.cer -nodes
NOTE: While converting PFX to PEM format, openssl will put all the Certificates and Private Key into a single file. You will need to open the file in Text editor and copy each Certificate & Private key(including the BEGIN/END statements) to its own individual text file and save them as certificate.cer, CAcert.cer, privateKey.key respectively.
-----BEGIN PRIVATE KEY-----
Saved as certificate.key
-----END PRIVATE KEY-----

Get the path of running Apache
$ ps -ef | grep apache
apache 12846 14590 0 Oct20 ? 00:00:00 /usr/sbin/apache2
Append -V
argument to the path
$ /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE
-D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"
Reference:
http://commanigy.com/blog/2011/6/8/finding-apache-configuration-file-httpd-conf-location
It could also be something as simple as Apache not being configured to start automatically on boot. Assuming you are on a Red Hat-like system such as CentOS or Fedora, the chkconfig –list command will show you which services are set to start for each runlevel. You should see a line like
httpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
If instead it says "off" all the way across, you can activate it with chkconfig httpd on. OR you can start apache manually from your panel.
In addition to all the answers if you still encounter some variation of the problem, edit the .env
file and set APP_URL
to your domain name as in:
APP_URL=similar_to_my_avatar_link
For reading date cells this method has proven to be robust so far:
private LocalDate readCellAsDate(final Row row, final int pos) {
if (pos == -1) {
return null;
}
final Cell cell = row.getCell(pos - 1);
if (cell != null) {
cell.setCellType(CellType.NUMERIC);
} else {
return null;
}
if (DateUtil.isCellDateFormatted(cell)) {
try {
return cell.getDateCellValue().toInstant().atZone(ZoneId.systemDefault()).toLocalDate();
} catch (final NullPointerException e) {
logger.error(e.getMessage());
return null;
}
}
return null;
}
To disable all access to sub dirs (safest) use:
<Directory full-path-to/USERS>
Order Deny,Allow
Deny from All
</Directory>

AddType application/x-httpd-php .php .phtml .php3
2 - Based on the extensions add a Regular Expression to FilesMatch (or LocationMatch)
<Directory full-path-to/USERS>
<FilesMatch "(?i)\.(php|php3?|phtml)$">
Order Deny,Allow
Deny from All
</FilesMatch>
</Directory>
Or use Location to match php files (I prefer the above files approach)
<LocationMatch "/USERS/.*(?i)\.(php3?|phtml)$">
Order Deny,Allow
Deny from All
</LocationMatch>
I had same issue, was due to multiple copies of ssl.conf In /etc/httpd/conf.d - There should only be one.
It's look like you are using an old version of slim(2.x). You can just add following lines to .htaccess and don't need to do anything in PHP scripts.
# Enable cross domain access control
SetEnvIf Origin "^http(s)?://(.+\.)?(domain_one\.com|domain_two\.net)$" REQUEST_ORIGIN=$0
Header always set Access-Control-Allow-Origin %{REQUEST_ORIGIN}e env=REQUEST_ORIGIN
Header always set Access-Control-Allow-Methods "GET, POST, PUT, DELETE"
Header always set Access-Control-Allow-Headers: Authorization
# Force to request 200 for options
RewriteEngine On
RewriteCond %{REQUEST_METHOD} OPTIONS
RewriteRule .* / [R=200,L]
For Apache 2.4.2: I was getting 403: Forbidden continuously when I was trying to access WAMP on my Windows 7 desktop from my iPhone on WiFi. On one blog, I found the solution - add Require all granted after Allow all in the <Directory> section. So this is how my <Directory> section looks like inside <VirtualHost>
<Directory "C:/wamp/www">
Options Indexes FollowSymLinks MultiViews Includes ExecCGI
AllowOverride All
Order Allow,Deny
Allow from all
Require all granted
</Directory>
Can you try changing "Allow from 127.0.0 192.168.1 ::1 localhost" to "Allow from all". If that fixes your problem, you need to be less restrict about where content can be requested from
You need to configure Apache (the webserver) to process PHP scripts as PHP. Check Apache's configuration. You need to load the module (the path may differ on your system):
LoadModule php5_module "c:/php/php5apache.dll"
And you also need to tell Apache what to process with PHP:
AddType application/x-httpd-php .php
Solved this by adding following
RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
RewriteCond %{REQUEST_FILENAME} -f [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^ - [L]
There shouldn't be any difference in gzip & deflate for decompression. Gzip is just deflate with a few dozen byte header wrapped around it including a checksum. The checksum is the reason for the slower compression. However when you're precompressing zillions of files you want those checksums as a sanity check in your filesystem. In addition you can utilize commandline tools to get stats on the file. For our site we are precompressing a ton of static data (the entire open directory, 13,000 games, autocomplete for millions of keywords, etc.) and we are ranked 95% faster than all websites by Alexa. Faxo Search. However, we do utilize a home grown proprietary web server. Apache/mod_deflate just didn't cut it. When those files are compressed into the filesystem not only do you take a hit for your file with the minimum filesystem block size but all the unnecessary overhead in managing the file in the filesystem that the webserver could care less about. Your concerns should be total disk footprint and access/decompression time and secondarily speed in being able to get this data precompressed. The footprint is important because even though disk space is cheap you want as much as possible to fit in the cache.
I'd the same error even after recompiling the modules.
But I solved it you just have to specify the absolute path of your phpize.
I did all of the suggested stuff here and my code still did not work because I was using curl
If you are using curl
in the php file, curl seems to reject all ssl traffic by default. A quick-fix that worked for me was to add:
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
before calling:
curl_exec():
in the php file.
I believe that this disables all verification of SSL certificates.
The answer of JasonW is fine. But since apache httpd 2.4.6 there is a alternative: mod_remoteip
All what you must do is:
Enable the module:
LoadModule remoteip_module modules/mod_remoteip.so
Add the following to your apache httpd config. Note that you must add this line not into the configuration of the proxy server. You must add this to the configuration of the proxy target httpd server (the server behind the proxy):
RemoteIPHeader X-Forwarded-For
See at http://httpd.apache.org/docs/trunk/mod/mod_remoteip.html for more informations and more options.
Please Note: The original poster was not specifically asking about PHP. All the php centric answers make large assumptions not relevant to the actual question.
The default error log as opposed to the scripts error logs usually has the (more) specific error. often it will be permissions denied or even an interpreter that can't be found.
This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error.
in perl if you forget
print "content-type: text/html\r\n\r\n";
you will get this error
There are many reasons for it. so please first check your error log and then provide some more information.
The default error log is often in /var/log/httpd/error_log
or /var/log/apache2/error.log
.
The reason you look at the default error logs (as indicated above) is because errors don't always get posted into the custom error log as defined in the virtual host.
Assumes linux and not necessarily perl
It's permission problem. It is not "classic" read/write permissions of apache user, but selinux one.
Apache cannot write to files labeled as httpd_sys_content_t
they can be only read by apache.
You have 2 possibilities:
label svn repository files as httpd_sys_content_rw_t
:
chcon -R -t httpd_sys_content_rw_t /path/to/your/svn/repo
set selinux boolean httpd_unified --> on
setsebool -P httpd_unified=1
I prefer 2nd possibility. You can play also with other selinux booleans connected with httpd
:
getsebool -a | grep httpd
On centOS7 I changed the file /etc/httpd/conf/httpd.conf
from AllowOverride None to AllowOverride All
i have found that similar issue on my system, and that was from skype installed before xampp installed. i got similar error. for fixing the error i followed these,
i wasn't need nothing to install or uninstall, and this worked for me in less then 1 minute.
cheers
In my case easiest way to get browser headers was to use php. It appends headers to file and prints them to test page.
<?php
$fp = fopen('m:/temp/requests.txt', 'a');
$time = $_SERVER['REQUEST_TIME'];
fwrite($fp, $time "\n");
echo "$time.<br>";
foreach (getallheaders() as $name => $value) {
$cur_hd = "$name: $value\n";
fwrite($fp, $cur_hd);
echo "$cur_hd.<br>";
}
fwrite($fp, "***\n");
fclose($fp);
?>
This could be one solution.

Open index.php
in www
folder and set
$suppress_localhost = false;
This will prepend http://localhost/
to your project links
I think the problem that it is showing code instead of the result is that it is not going to local host . recheck what address u r going in. are u going to a local file directory or to the local host.
from the screenshot u sent it is going to ur computer not to the localhost.
"file:/// " it should be "localhost/"
First enable mod_headers
on your server, then you can use header directive in both Apache conf and .htaccess
.
mod_headers
a2enmod headers
.htaccess
fileHeader add Access-Control-Allow-Origin "*"
Header add Access-Control-Allow-Headers "origin, x-requested-with, content-type"
Header add Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS"
I found Maven Integration for Eclipse here.
http://download.eclipse.org/technology/m2e/releases
After installing restart eclipse. Worked for me running Eclipse Juno.
restorecon
command works as below :
restorecon -v -R /var/www/html/
This is normal if you see it. Since it is the first virtual host entry, it will show local host.
Let’s say for example you didn't want that page to show. All you want to show is the "Apache, it works" page, so you would make a vhost entry before mysite.local as local host and point it to the "it works" page.
But this is normal. I had this problem before, so don't worry!
So after running brew install mcrypt php
, I had to install php-mcrypt via pecl:
pecl install mcrypt-1.0.1
At the time of writing, mcrypt does not have a stable pecl release, 1.0.1 being the current release for php 7.2 and 7.3, and brew install php
will install php 7.2.
This worked for me on all browsers:
As far as I'm aware of a simple meta refresh also works without causing errors:
<meta http-equiv="refresh" content="0;URL='http://www.yourdomain.com/path'">
TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm
service.
The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.
To restart the service:
Note: prepend sudo if not root
Using SysV Init scripts directly:
/etc/init.d/php-fpm restart # typical
/etc/init.d/php5-fpm restart # debian-style
/etc/init.d/php7.0-fpm restart # debian-style PHP 7
Using service wrapper script
service php-fpm restart # typical
service php5-fpm restart # debian-style
service php7.0-fpm restart. # debian-style PHP 7
Using Upstart (e.g. ubuntu):
restart php7.0-fpm # typical (ubuntu is debian-based) PHP 7
restart php5-fpm # typical (ubuntu is debian-based)
restart php-fpm # uncommon
Using systemd (newer servers):
systemctl restart php-fpm.service # typical
systemctl restart php5-fpm.service # uncommon
systemctl restart php7.0-fpm.service # uncommon PHP 7
Or whatever the equivalent is on your system.
The above commands taken directly from this server fault answer
Just in case this helps anyone else:
If you're going to be adding the TimeOut
directive, and your website uses multiple vhosts (eg. one for port 80, one for port 443), then don't forget to add the directive to all of them!
You cannot use the Directory directive in .htaccess. However if you create a .htaccess file in the /system directory and place the following in it, you will get the same result
#place this in /system/.htaccess as you had before
deny from all
Yes, its possible and its fairly easy.
When you're ready to press run, if you go to "localhost:8080/< page_name > " you'll see your page.

Reinstalling the software fixes the issue, just make sure not to delete the htdocs folder in the process.
Before making the npm build,
1) Go to your React project root folder and open package.json
.
2) Add "homepage" attribute to package.json
if you want to provide absolute path
"homepage": "http://hostName.com/appLocation",
"name": "react-app",
"version": "1.1.0",
if you want to provide relative path
"homepage": "./",
"name": "react-app",
Using relative path method may warn a syntax validation error in your IDE. But the build is made without any errors during compilation.
3) Save the package.json
, and in terminal run npm run-script build
4) Copy the contents of build/
folder to your server directory.
PS: It is easy to use relative path method if you want to change the build file location in your server frequently.
I was having a similar problem. PHP was working on my sites configured by virtualmin but not for phpmyadmin. PHPMyAdmin would not execute and the file was being downloaded by the browser. Everything I was reading was saying that libapache2-mod-php5 was not installed but I knew it was... so the thing to do was to purge it and reinstall.
sudo apt-get purge libapache2-mod-php5
sudo apt-get install libapache2-mod-php5
sudo apt-get purge phpmyadmin
sudo apt-get install phpmyadmin
sudo /etc/init.d/apache2 restart
Either two different IP addresses (like recommended) or one web server is reverse-proxying the other (which is listening on a port <>80).
For instance: Apache listens on port 80, IIS on port 8080. Every http request goes to Apache first (of course). You can then decide to forward every request to a particular (named virtual) domain or every request that contains a particular directory (e.g. http://www.example.com/winapp/) to the IIS.
Advantage of this concept is that you have only one server listening to the public instead of two, you are more flexible as with two distinct servers.
Drawbacks: some webapps are crappily designed and a real pain in the ass to integrate into a reverse-proxy infrastructure. A working IIS webapp is dependent on a working Apache, so we have some inter-dependencies.

Now You need to understand permissions and options in ubuntu.
Under advanced settings of firefox you should be able to set the encryption. By default SSL3.0 and TLS1.0 should be checked, so if firefox is trying to create ssl 3.0 connectons try unchecking the ssl 3.0s setting.
if that doesn't work, try searching the about:config page for "ssl2" My Firefox has settings with ssl2 set to false by default...
Weird, just had simmilar issue, went here http://www.microsoft.com/en-us/download/confirmation.aspx?id=30679 downloaded and installed vcredist_x86 (i'm using 32bit apache) and it works like a charm.
If you are using RHEL/CentOS 7 (the OP was not, but I thought I'd share the solution for my case), then you will need to use firewalld instead of the iptables service mentioned in other answers.
firewall-cmd --zone=public --add-port=80/tcp --permanent
firewall-cmd --reload
And then check that it is running with:
firewall-cmd --permanent --zone=public --list-all
It should list 80/tcp
under ports
To check configuration files for syntax errors:
# Red Hat-based (Fedora, CentOS) and OSX
httpd -t
# Debian-based (Ubuntu)
apache2ctl -t
# MacOS
apachectl -t
To list all virtual hosts, and their locations:
# Red Hat-based (Fedora, CentOS) and OSX
httpd -S
# Debian-based (Ubuntu)
apache2ctl -S
# MacOS
apachectl -S
I know it's an old question and it has been solved already but for me the Tomcat conf/tomcat-users.xml file was created with a different encoding from the rest of the configuration files. The first line of that file looked like this:
<?xml version='1.0' encoding='cp65001'?>
All I had to do to solve the issue was change that line for:
<?xml version="1.0" encoding="UTF-8"?>
And voila.
I have no idea what 'cp65001'
means or why it was created like that.
Maybe this will help other users facing the same issue.
I am using xampp 1.7.3. Using inspiration from here: xampp 1.7.3 upgrade broken virtual hosts access forbidden
INSTEAD OF add <Directory> .. </Directory>
in httpd-vhosts.conf, I add it in httpd.conf right after <Directory "D:/xampplite/cgi-bin"> .. </Directory>
.
Here is what I add in httpd.conf:
<Directory "D:/CofeeShop">
AllowOverride All

And here is what I add in httpd-vhosts.conf
<VirtualHost *:8001>
ServerAdmin [email protected]

I also add Listen 8001
in httpd.conf to complete my setting.
Hope it helps
And I simply got this error because I used a totally different DocumentRoot directory.
My main DocumentRoot was the default /var/www/html
and on the VirtualHost I used /sites/example.com
I have created a link on /var/www/html/example.com
(to /sites/example.com
).
DocumentRoot was set to /var/www/html/example.com
It worked like a charm.
You need httpclient.jar and httpcore.jar. You can download them from here.
http://archive.apache.org/dist/httpcomponents/httpclient/binary/
I used
a2ensite default-ssl
and it worked like a charm.
If you want to force e.g. phpmyadmin to use SSL/https you will run into this problem if this link is missing.
Before you can fix anything you need to know which service has not started, Apache or MySQL.
As the TEST PORT 80 utility is saying Apache is running its probably the MySQL service that has not started. Unless you have another Apache running!
So which service has not started???
If the wampmanager icon is not GREEN then one of the services ( Apache/MySQL ) has not started properly.
How to tell which service is not running if the wampmanager icon is orange.
Left click the wampmanager icon to reveal the menu-> Apache -> Service If the Start/Resume service menu is Green then Apache IS NOT running.
Left click the wampmanager icon to reveal the menu-> MySQL -> Service If the Start/Resume service menu is Green then MySQL IS NOT running.
If Apache is the service that is not running it is normally, but not always, because something else has captured port 80.
Now do, Left click the wampmanager icon to reveal the menu-> Apache -> Service -> Test port 80 This will launch a command window and display some information about what, if anything is using port 80.
Whatever it is should be re-configured to not use port 80 or uninstalled if you are not using it.
If port 80 is not the problem look for errors in the appropriate error log ( use the wamp manager menus to view the error logs )
If these do not exists or show no errors then also check the Windows Event Viewer Start -> Administrative Tools -> Event Viewer And look in the 'Windows Logs' -> Application' section accessed from the menu on the left of the dialog for error messages from Apache and or MySQL.
Check the mysql error log by using the menus
wampmanager->MySQL->error log
Check the Windows Event log for messages from MYSQL
Check you dont have another MYSQL Server instance running.
How to Configure SKYPE so it does not require port 80 or 443
Run SKYPE then using the menus do this: Tools -> Options -> Advanced -> Connection Un-Check the checkbox next to 'Use port 80 and 443 as alternatives for incomming connections' Now restart SKYPE for these changes to take effect.
If you are running Windows 8 SKYPE comes as an app and this cannot ( as yet ) be configured in this way. However if you uninstall the SKYPE app and install SKYPE in the old way, you can reconfigure it, and it works just as well.
Have you tried using Linux Installer to get a full Debian build on the phone? It's billed as being able to run a full LAMP environment in about 300M and has gotten some good reviews.
You just need 775
for /var/www/html
as long as you are logging in as myuser. The 7
octal in the middle (which is for "group" acl) ensures that the group has permission to read/write/execute. As long as you belong to the group that owns the files, "myuser" should be able to write to them. You may need to give group permissions to all the files in the docuemnt root, though:
chmod -R g+w /var/www/html
Download commons-net binary from here. Extract the files and reference the commons-net-x.x.jar file.
Attach gdb to one of the httpd child processes and reload or continue working and wait for a crash and then look at the backtrace. Do something like this:
$ ps -ef|grep httpd

501 690 681 0 10:38pm ?? 0:00.02 /Applications/MAMP/Library/bin/httpd -k start
...
Now attach gdb to one of the child processes, in this case PID 690 (columns are UID, PID, PPID, ...)
$ sudo gdb
(gdb) attach 690
Attaching to process 690.

Continuing.
Wait for crash... then:
(gdb) backtrace
Or
(gdb) backtrace full
Should give you some clue what's going on. If you file a bug report you should include the backtrace.
If the crash is hard to reproduce it may be a good idea to configure Apache to only use one child processes for handling requests. The config is something like this:
StartServers 1
MinSpareServers 1
MaxSpareServers 1
On your XAMPP control panel, next to apache, select the "Config" option and select the first file (httpd.conf):
there, look for the "listen" line (you may use the find tool in the notepad) and there must be a line stating "Listen 80". Note: there are other lines with "listen" on them but they should be commented (start with a #), the one you need to change is the one saying exactly "listen 80". Now change it to "Listen 1337".
Start apache now.
If the error subsists, it's because there's another port that's already in use. So, select the config option again (next to apache in your xampp control panel) and select the second option this time (httpd-ssl.conf):
there, look for the line "Listen 443" and change it to "Listen 7331".
Start apache, it should be working now.
Check the comparability, if you are using java 8 then use tomcat 9, if you are using java 7 then use tomcat 7. and also set the JAVA_HOME till C:\Program Files\Java\jdk1.8.0_101, not with bin.
I received the same error above and what caused it for me was that in the file 'httpd-vhosts.conf' I put a comment inside the <Directory>
tags like this...
<Directory "*PATH TO MY FOLDER*...">

</Directory>
Once I removed the comment, Apache started. I guess I should have put the comment on its own line. I just thought, like other web code, it could be there.

I think it has more to do with how Windows is configured as hinted by this response: Java -Xmx Option
Some more testing: I was able to allocate 1300MB on an old Windows XP machine with only 768MB physical RAM (plus virtual memory). On my 2GB RAM machine I can only get 1220MB. On various other corporate machines (with older Windows XP) I was able to get 1400MB. The machine with a 1220MB limit is pretty new (just purchased from Dell), so maybe it has newer (and more bloated) Windows and DLLs (it's running Window XP Pro Version 2002 SP2).
Is there a specific reason why you need to use an array? If you don't know the size before hand you might want to use List<String>
List<String> list = new List<String>();
list.Add("Hello");
list.Add("world");
list.Add("!");
Console.WriteLine(list[2]);
Will give you an output of
!
MSDN - List(T) for more information
os.chdir()
is the Pythonic version of cd
.
I think the best way to do this is:
t = (1,2,3)
print "This is a tuple: %s" % str(t)
If you're familiar with printf style formatting, then Python supports its own version. In Python, this is done using the "%" operator applied to strings (an overload of the modulo operator), which takes any string and applies printf-style formatting to it.
In our case, we are telling it to print "This is a tuple: ", and then adding a string "%s", and for the actual string, we're passing in a string representation of the tuple (by calling str(t)).
If you're not familiar with printf style formatting, I highly suggest learning, since it's very standard. Most languages support it in one way or another.
Try this;
var data = "";
data = "<option value = Some value> Some Option </option>";
options = [];
options.push(data);
select = document.getElementById("drop_down_id");
select.innerHTML = optionsHTML.join('\n');

For those who can't rely on Chronometer, I made a utility class out of one of the suggestions:
public class TimerTextHelper implements Runnable {
private final Handler handler = new Handler();
private final TextView textView;
private volatile long startTime;
private volatile long elapsedTime;
public TimerTextHelper(TextView textView) {
this.textView = textView;
}
@Override
public void run() {
long millis = System.currentTimeMillis() - startTime;
int seconds = (int) (millis / 1000);
int minutes = seconds / 60;
seconds = seconds % 60;
textView.setText(String.format("%d:%02d", minutes, seconds));
if (elapsedTime == -1) {
handler.postDelayed(this, 500);
}
}
public void start() {
this.startTime = System.currentTimeMillis();
this.elapsedTime = -1;
handler.post(this);
}
public void stop() {
this.elapsedTime = System.currentTimeMillis() - startTime;
handler.removeCallbacks(this);
}
public long getElapsedTime() {
return elapsedTime;
}
}
to use..just do:
TimerTextHelper timerTextHelper = new TimerTextHelper(textView);
timerTextHelper.start();
.....
timerTextHelper.stop();
long elapsedTime = timerTextHelper.getElapsedTime();

For those of us accomplishing this with Angular JS, I used a directive
HTML:
<textarea elastic ng-model="someProperty"></textarea>
JS:
.directive('elastic', [
'$timeout',
function($timeout) {
return {
restrict: 'A',
link: function($scope, element) {
$scope.initialHeight = $scope.initialHeight || element[0].style.height;
var resize = function() {
element[0].style.height = $scope.initialHeight;
element[0].style.height = "" + element[0].scrollHeight + "px";
};
element.on("input change", resize);
$timeout(resize, 0);
}
};
}
]);
$timeout
queues an event that will fire after the DOM loads, which is what's necessary to get the right scrollHeight (otherwise you'll get undefined
)
const
always modifies the thing that comes before it (to the left of it), EXCEPT when it's the first thing in a type declaration, where it modifies the thing that comes after it (to the right of it).
So these two are the same:
int const *i1;
const int *i2;
they define pointers to a const int
. You can change where i1
and i2
points, but you can't change the value they point at.
This:
int *const i3 = (int*) 0x12345678;
defines a const
pointer to an integer and initializes it to point at memory location 12345678. You can change the int
value at address 12345678, but you can't change the address that i3
points to.
how about just getting the length of char in your EditText and display it?
something along the line of
tv.setText(s.length() + " / " + String.valueOf(charCounts));
If I'm not using any category then how can I use this code? Actually, I want to use this code for custom post type.
I came to this page with the same question in mind, but it worked for me!, Just thought to update here , may be helpful for someone later!!

Both Python dict
(before Python 3.7) and JSON object are unordered collections. You could pass sort_keys
parameter, to sort the keys:
>>> import json
>>> json.dumps({'a': 1, 'b': 2})
'{"b": 2, "a": 1}'
>>> json.dumps({'a': 1, 'b': 2}, sort_keys=True)
'{"a": 1, "b": 2}'
If you need a particular order; you could use collections.OrderedDict
:
>>> from collections import OrderedDict
>>> json.dumps(OrderedDict([("a", 1), ("b", 2)]))
'{"a": 1, "b": 2}'
>>> json.dumps(OrderedDict([("b", 2), ("a", 1)]))
'{"b": 2, "a": 1}'
Since Python 3.6, the keyword argument order is preserved and the above can be rewritten using a nicer syntax:
>>> json.dumps(OrderedDict(a=1, b=2))
'{"a": 1, "b": 2}'
>>> json.dumps(OrderedDict(b=2, a=1))
'{"b": 2, "a": 1}'
See PEP 468 – Preserving Keyword Argument Order.
If your input is given as JSON then to preserve the order (to get OrderedDict
), you could pass object_pair_hook
, as suggested by @Fred Yankowski:
>>> json.loads('{"a": 1, "b": 2}', object_pairs_hook=OrderedDict)
OrderedDict([('a', 1), ('b', 2)])
>>> json.loads('{"b": 2, "a": 1}', object_pairs_hook=OrderedDict)
OrderedDict([('b', 2), ('a', 1)])
With Jquery you can do this with one simple codeline.

ruby = "puts YAML.load_file('%s').to_json" % fn
j = commands.getstatusoutput('ruby -ryaml -rjson -e "%s"' % ruby)
return json.loads(j[1])

If your database supports arrays, you can also implement a lineage column or materialized path as an array of parent ids.
Specifically with Postgres you can then use the set operators to query the hierarchy, and get excellent performance with GIN indices. This makes finding parents, children, and depth pretty trivial in a single query. Updates are pretty manageable as well.
I have a full write up of using arrays for materialized paths if you're curious.
You can use a LEFT JOIN with a "VALUES ('f',1),('p',2),('a',3),('i',4)" and use the second column in your order-by expression. Postgres will use a Hash Join which will be much faster than a huge CASE if you have a lot of values. And it is easier to autogenerate.
If this ordering information is fixed, then it should have its own table.

In C, the type of a character constant like 'a'
is actually an int
, with size of 4 (or some other implementation-dependent value). In C++, the type is char
, with size of 1. This is one of many small differences between the two languages.
This is really easy using a JavaScript library, e.g. using jQuery you could write:
$(document).ready(function(){
$.ajax({ url: "database/update.html",
context: document.body,
success: function(){
alert("done");
}});
});
Without jQuery, the simplest version might be as follows, but it does not account for browser differences or error handling:
<html>
<body onload="updateDB();">
</body>
<script language="javascript">
function updateDB() {
var xhr = new XMLHttpRequest();
xhr.open("POST", "database/update.html", true);
xhr.send(null);
/* ignore result */
}
</script>

StandardScaler performs the task of Standardization. Usually a dataset contains variables that are different in scale. For e.g. an Employee dataset will contain AGE column with values on scale 20-70 and SALARY column with values on scale 10000-80000.
As these two columns are different in scale, they are Standardized to have common scale while building machine learning model.
This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.
The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.
var pinIcon = new google.maps.MarkerImage(
"http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
null, /* size is determined at runtime */
null, /* origin is 0,0 */
null, /* anchor is bottom center of the scaled image */
new google.maps.Size(42, 68)
);
As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.
Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:
The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null
. In other words, leaving the anchor null ensures the tip points where it is supposed to point.
However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.
By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.
var pinShadow = new google.maps.MarkerImage(
"http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
null,
null,
/* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
new google.maps.Point(40, 110),
new google.maps.Size(120, 110));

In case you want to improve the commit message with header and body after you created the commit, you can reword it. This approach is more useful because you know what the code does only after you wrote it.
git rebase -i origin/master
Then, your commits will appear:
pick e152ce2 Update framework
pick ffcf91e Some magic
pick fa672e1 Update comments
Select the commit you want to reword and save.
pick e152ce2 Update framework
reword ffcf91e Some magic
pick fa672e1 Update comments
Now, you have the opportunity to add header and body, where the first line will be the header.

Redesign laws of physics with a pinch of imagination. Open a wormhole in 23 dimensions. Add protection to avoid high instability.
The reason behind this is that meanwhile creating your own class, you had also accepted to create a default class as prescribed by your IDE and after writing your code in your own class, you are getting such an error. In order to eliminate this, go to the PROJECT folder ? src

After that, run your program and it will definitely run without any error.

I tested what @Samy Dindane suggested in the comment on the OP.
I believe it works, try
git fetch <remote_name> <remote_branch>:<local_branch>
git checkout <local_branch>
Here's an example for a fictitious remote repository named foo
with a branch named bar
where I create a local branch bar
tracking the remote:
git fetch foo bar:bar
git checkout bar
What I do is create a view that performs the same select as the table variable and link that view into the second view. So a view can select from another view. This achieves the same result
Update
Based on Manipulating the browser history, passing the empty string as second parameter of pushState
method (aka title) should be safe against future changes to the method, so it's better to use pushState
like this:
history.pushState(null, '', '/en/step2');
You can read more about that in mentioned article
Original Answer
Use history.pushState
like this:
history.pushState(null, null, '/en/step2');
Update 2 to answer Idan Dagan's comment:
Why not using
history.replaceState()
?
From MDN
history.replaceState() operates exactly like history.pushState() except that replaceState() modifies the current history entry instead of creating a new one
That means if you use replaceState
, yes the url will be changed but user can not use Browser's Back button to back to prev. state(s) anymore (because replaceState
doesn't add new entry to history) and it's not recommended and provide bad UX.
Update 3 to add window.onpopstate
So, as this answer got your attention, here is additional info about manipulating the browser history, after using pushState
, you can detect the back/forward button navigation by using window.onpopstate
like this:
window.onpopstate = function(e) {
// ...
};
As the first argument of pushState
is an object, if you passed an object
instead of null
, you can access that object in onpopstate
which is very handy, here is how:
window.onpopstate = function(e) {
if(e.state) {
console.log(e.state);
}
};
Update 4 to add Reading the current state:
When your page loads, it might have a non-null state object, you can read the state of the current history entry without waiting for a popstate
event using the history.state
property like this:
console.log(history.state);
Bonus: Use following to check history.pushState
support:
if (history.pushState) {
// \o/
}
EDMX model won't work with EF7 but I've found a Community/Professional product which seems to be very powerfull : http://www.devart.com/entitydeveloper/editions.html
The nested class doesn't know about the outer class, and protected
doesn't help. You'll have to pass some actual reference to objects of the nested class type. You could store a foo*
, but perhaps a reference to the integer is enough:
class Outer
{
int n;
public:
class Inner
{
int & a;
public:
Inner(int & b) : a(b) { }
int & get() { return a; }
};
// ... for example:
Inner inn;
Outer() : inn(n) { }
};
Now you can instantiate inner classes like Inner i(n);
and call i.get()
.

to add (eclipse->maven) plugin specific options.
307 came about because user agents adopted as a de facto behaviour to take POST requests that receive a 302 response and send a GET request to the Location response header.
That is the incorrect behaviour — only a 303 should cause a POST to turn into a GET. User agents should (but don't) stick with the POST method when requesting the new URL if the original POST request returned a 302.
307 was introduced to allow servers to make it clear to the user agent that a method change should not be made by the client when following the Location response header.
Try this:
function createcodes() {
$('.authors-list tr').each(function () {
//processing this row
//how to process each cell(table td) where there is checkbox
$(this).find('td input:checked').each(function () {
// it is checked, your code here...
});
});
}
Two things are happening here.
Bootstrap uses a grid system and the .container class is defined in its own CSS. The grid has to exist within a container class DIV. The container DIV is just an indication to Bootstrap that the grid within has that parent. Therefore, you cannot set the height of a container.
What you want to do is the following:
<div class="container-fluid"> <!-- this is to make it responsive to your screen width -->
<div class="row">
<div class="col-md-4 myClassName"> <!-- myClassName is defined in my CSS as you defined your container -->
<img src="#.jpg" height="200px" width="300px">
</div>
</div>
</div>
Here you can find more info on the Bootstrap grid system.
That being said, if you absolutely MUST override the Bootstrap CSS then I would try using the "!important" clause to my CSS definition as such...
.container {
padding-right: 15px;
padding-left: 15px;
margin-right: auto;
margin-left: auto;
max-width: 900px;
overflow:hidden;
min-height:0px !important;
}
But I have always found that the "!important" clause just makes for messy CSS.
Relevant reading: The Open-Closed Principle by Bob Martin.
Key quote:
Software Entities (Classes, Modules, Functions, etc.) should be open for Extension, but closed for Modification.
The final
keyword is the means to enforce this in Java, whether it's used on methods or on classes.
I used Mike Wasson's answer before I updated all the NuGets in my webapi mvc4 project. Once I did, I had to re-write the file upload action:
public Task<HttpResponseMessage> Upload(int id)
{
HttpRequestMessage request = this.Request;
if (!request.Content.IsMimeMultipartContent())
{
throw new HttpResponseException(new HttpResponseMessage(HttpStatusCode.UnsupportedMediaType));
}
string root = System.Web.HttpContext.Current.Server.MapPath("~/App_Data/uploads");
var provider = new MultipartFormDataStreamProvider(root);
var task = request.Content.ReadAsMultipartAsync(provider).
ContinueWith<HttpResponseMessage>(o =>
{
FileInfo finfo = new FileInfo(provider.FileData.First().LocalFileName);
string guid = Guid.NewGuid().ToString();
File.Move(finfo.FullName, Path.Combine(root, guid + "_" + provider.FileData.First().Headers.ContentDisposition.FileName.Replace("\"", "")));
return new HttpResponseMessage()
{
Content = new StringContent("File uploaded.")
};
}
);
return task;
}
Apparently BodyPartFileNames is no longer available within the MultipartFormDataStreamProvider.
CSS relates to visual styling and not behaviour, so the answer is no really.
You could however either use javascript to modify the behaviour or change the styling of the span in question so that it doesn't have the pointy finger, underline, etc. Styling it like that will still leave it clickable.
Even better, change your markup so that it reflects what you want it to do.
This should do it:
<style>
body {
background:url(bg.jpg) fixed no-repeat bottom right;
}
</style>
Another way
=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH({"Gingrich","Obama","Romney"},C1)))))>0,"1","")
Also, if you keep a list of values in, say A1 to A3, then you can use
=IF(SUMPRODUCT(--(NOT(ISERR(SEARCH($A$1:$A$3,C1)))))>0,"1","")
The wildcards are not necessary at all in the Search() function, since Search() returns the position of the found string.
If you are running server already, don't forget to use http:// in the API call. This might cause a serious trouble.
The .net framework supports JSON through JavaScriptSerializer. Here is a good example to get you started.
using System.Collections.Generic;
using System.Web.Script.Serialization;
namespace GoogleTranslator.GoogleJSON

public class FooTest

public void Test()
{
const string json = @"{
""DisplayFieldName"" : ""ObjectName"",
""FieldAliases"" : {
""ObjectName"" : ""ObjectName"",
""ObjectType"" : ""ObjectType""
},
""PositionType"" : ""Point"",
""Reference"" : {
""Id"" : 1111
},
""Objects"" : [
{
""Attributes"" : {
""ObjectName"" : ""test name"",
""ObjectType"" : ""test type""
},
""Position"" :
{
""X"" : 5,
""Y"" : 7
}
}
]
}";
var ser = new JavaScriptSerializer();
ser.Deserialize<Foo>(json);
}
}
public class Foo
{
public Foo() { Objects = new List<SubObject>(); }
public string DisplayFieldName { get; set; }
public NameTypePair FieldAliases { get; set; }
public PositionType PositionType { get; set; }
public Ref Reference { get; set; }
public List<SubObject> Objects { get; set; }
}
public class NameTypePair
{
public string ObjectName { get; set; }
public string ObjectType { get; set; }
}
public enum PositionType { None, Point }
public class Ref
{
public int Id { get; set; }
}
public class SubObject
{
public NameTypePair Attributes { get; set; }
public Position Position { get; set; }

public class Position
{

In OS X 10.6, the open
command was enhanced to allow passing of arguments to the application:
open ./AppName.app --args -AppCommandLineArg
But for older versions of Mac OS X, and because app bundles aren't designed to be passed command line arguments, the conventional mechanism is to use Apple Events for files like here for Cocoa apps or here for Carbon apps. You could also probably do something kludgey by passing parameters in using environment variables.
Here's a function I wrote which works similarly to the Unix time
command:
function time {
Param(
[Parameter(Mandatory=$true)]
[string]$command,
[switch]$quiet = $false
)
$start = Get-Date
try {
if ( -not $quiet ) {
iex $command | Write-Host
} else {
iex $command > $null
}
} finally {
$(Get-Date) - $start
}
}

Based on your comment to Haim, is this a file on your own server? If so, you need to use the file system path, not url (e.g. file_exists( '/path/to/images/thumbnail.jpg' )
).
@Stephen Bailey
To complete your answer, you can also delegate the user rights to the project manager, through a plain text file in your repository.
To do that, you set up your SVN database with a default authz
file containing the following:
###########################################################################
# The content of this file always precedes the content of the
# $REPOS/admin/acl_descriptions.txt file.
# It describes the immutable permissions on main folders.
###########################################################################
[groups]
svnadmins = xxx,yyy,....
[/]
@svnadmins = rw
* = r
[/admin]
@svnadmins = rw
@projadmins = r
* =
[/admin/acl_descriptions.txt]
@projadmins = rw
This default authz
file authorizes the SVN administrators to modify a visible plain text file within your SVN repository, called '/admin/acl_descriptions.txt', in which the SVN administrators or project managers will modify and register the users.
Then you set up a pre-commit hook which will detect if the revision is composed of that file (and only that file).
If it is, this hook's script will validate the content of your plain text file and check if each line is compliant with the SVN syntax.
Then a post-commit hook will update the \conf\authz
file with the concatenation of:
authz
file presented above/admin/acl_descriptions.txt
The first iteration is done by the SVN administrator, who adds:
[groups]
projadmins = zzzz
He commits his modification, and that updates the authz
file.
Then the project manager 'zzzz' can add, remove or declare any group of users and any users he wants.
He commits the file and the authz
file is updated.
That way, the SVN administrator does not have to individually manage any and all users for all SVN repositories.
You probably already know about $(document).ready(...). What you need is a preloading mechanism; something that fetches data (text or images or whatever) before showing it off. This can make a site feel much more professional.
Take a look at jQuery.Preload (there are others). jQuery.Preload has several ways of triggering preloading, and also provides callback functionality (when the image is preloaded, then show it). I have used it heavily, and it works great.
Here's how easy it is to get started with jQuery.Preload:
$(function() {
// First get the preload fetches under way
$.preload(["images/button-background.png", "images/button-highlight.png"]);
// Then do anything else that you would normally do here
doSomeStuff();
});

I don't want to name names, but someone appears to be completely wrong. The referenced standards body stated the following: submissions 465 tcp Message Submission over TLS protocol [IESG] [IETF_Chair] 2017-12-12 [RFC8314]
If you are so inclined, you may wish to read the referenced RFC.
This seems to clearly imply that port 465 is the best way to force encrypted communication and be sure that it is in place. Port 587 offers no such guarantee.
Do below steps :
Check the version of chrome browser.
download chromedriver of same version from https://sites.google.com/a/chromium.org/chromedriver/
Give correct path in the pycharm and run the code.
Added a little bit more functionality to the example of Aravind Voggu:
def progressBar(name, value, endvalue, bar_length = 50, width = 20):
percent = float(value) / endvalue
arrow = '-' * int(round(percent*bar_length) - 1) + '>'
spaces = ' ' * (bar_length - len(arrow))
sys.stdout.write("\r{0: <{1}} : [{2}]{3}%".format(\
name, width, arrow + spaces, int(round(percent*100))))
sys.stdout.flush()
if value == endvalue:
sys.stdout.write('\n\n')
Now you are able to generate multiple progressbars without replacing the previous one.
I've also added name
as a value with a fixed width.
For two loops and two times the use of
progressBar()
the result will look like:
string strgroupids = string.Empty;
groupIds.ForEach(g =>
{
strgroupids = strgroupids + g.ToString() + ",";
});
strgroupids = strgroupids.Substring(0, strgroupids.Length - 1);
Note that the use of ForEach
here is normally considered "wrong" (read for example http://blogs.msdn.com/b/ericlippert/archive/2009/05/18/foreach-vs-foreach.aspx)
Using some LINQ:
string strgroupids = groupIds.Aggregate(string.Empty, (p, q) => p + q + ',');
strgroupids = strgroupids.Substring(0, str1.Length - 1);
Without end-substringing:
string strgroupids = groupIds.Aggregate(string.Empty, (p, q) => (p != string.Empty ? p + "," + q : q.ToString()));
In ruby Integer class, to_s is defined to receive non required argument radix called base
, pass 2 if you want to receive binary representation of a string.
Here is a link for an official documentation of String#to_s
1.upto(10).each { |n| puts n.to_s(2) }
UPDATE for v1.1:
Rather than giving q="search_string"
give it q="hashtag"
in URL encoded form to return results with HASHTAG ONLY. So your query would become:
GET https://api.twitter.com/1.1/search/tweets.json?q=%23freebandnames
%23
is URL encoded form of #
. Try the link out in your browser and it should work.
You can optimize the query by adding since_id
and max_id
parameters detailed here. Hope this helps !
Note: Search API is now a OAUTH authenticated call, so please include your access_tokens to the above call
Updated

You say you have an index, the explain says otherwise. However, if you really do, this is how to continue:
If you have an index on the column, and MySQL decides not to use it, it may by because:
ANALYZE TABLE
helps.In the case of (2) or (3), you could coax MySQL into using the index by index hint sytax, but if you do, be sure run some tests to determine whether it actually improves performance to use the index as you hint it.
Hi i wrote this general function to generate a dummy variable which essentially replicates the replace function in Stata.
If x is the data frame is x and i want a dummy variable called a
which will take value 1
when x$b
takes value c
introducedummy<-function(x,a,b,c){
g<-c(a,b,c)
n<-nrow(x)
newcol<-g[1]
p<-colnames(x)
p2<-c(p,newcol)
new1<-numeric(n)
state<-x[,g[2]]
interest<-g[3]
for(i in 1:n){
if(state[i]==interest){
new1[i]=1
}
else{
new1[i]=0
}
}
x$added<-new1
colnames(x)<-p2
x
}
$('div[imageId="imageN"]').each(function() {
// `this` is the div
});
To check for the sole existence of the attribute, no matter which value, you could use ths selector instead: $('div[imageId]')
This might be caused by HHH-10876 which got fixed so make sure you update to:
Those commands use different output streams. By default both messages will be printed on console but it's possible for example to redirect one or both of these to a file.
java MyApp 2>errors.txt
This will redirect System.err
to errors.txt
file.
My answer will scroll even when overflow:hidden;
, using jQuery:
For example, scroll horizontally with the mouse wheel:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
<script type='text/javascript' src='/js/jquery.mousewheel.min.js'></script>
<script type="text/javascript">
$(function() {
$("YourSelector").mousewheel(function(event, delta) {
this.scrollLeft -= (delta * 30);
event.preventDefault();
});
});
</script>
This is a late answer but if anyone reading this question is using razor, what you should remember is that razor encodes everything by default, but by using MvcHtmlString
in your html helpers you can tell razor that it doesn't need to encode it.
If you want razor to not encode a string use
@Html.Raw("<span>hi</span>")
Decompiling Raw(), shows us that it's wrapping the string in a HtmlString
public IHtmlString Raw(string value) {
return new HtmlString(value);
}
"HtmlString only exists in ASP.NET 4.
MvcHtmlString was a compatibility shim added to MVC 2 to support both .NET 3.5 and .NET 4. Now that MVC 3 is .NET 4 only, it's a fairly trivial subclass of HtmlString presumably for MVC 2->3 for source compatibility." source
After trying many tutorials to configure my Ubuntu 16.04 LTS behind a authenticated proxy, it worked with these steps:
Edit /etc/wgetrc
:
$ sudo nano /etc/wgetrc
Uncomment these lines:
#https_proxy = http://proxy.yoyodyne.com:18023/
#http_proxy = http://proxy.yoyodyne.com:18023/
#ftp_proxy = http://proxy.yoyodyne.com:18023/
#use_proxy = on
Change http://proxy.yoyodyne.com:18023/
to http://username:password@domain:port/
IMPORTANT: If it still doesn't work, check if your password has special characters, such as
#
,@
, ... If this is the case, escape them (for example, replacepassw@rd
withpassw%40rd
).
Prior to Android KitKat you have to root your device to install new certificates.
From Android KitKat (4.0) up to Nougat (7.0) it's possible and easy. I was able to install the Charles Web Debbuging Proxy cert on my un-rooted device and successfully sniff SSL traffic.
Extract from http://wiki.cacert.org/FAQ/ImportRootCert
Before Android version 4.0, with Android version Gingerbread & Froyo, there was a single read-only file ( /system/etc/security/cacerts.bks ) containing the trust store with all the CA ('system') certificates trusted by default on Android. Both system apps and all applications developed with the Android SDK use this. Use these instructions on installing CAcert certificates on Android Gingerbread, Froyo, ...
Starting from Android 4.0 (Android ICS/'Ice Cream Sandwich', Android 4.3 'Jelly Bean' & Android 4.4 'KitKat'), system trusted certificates are on the (read-only) system partition in the folder '/system/etc/security/' as individual files. However, users can now easily add their own 'user' certificates which will be stored in '/data/misc/keychain/certs-added'.
System-installed certificates can be managed on the Android device in the Settings -> Security -> Certificates -> 'System'-section, whereas the user trusted certificates are manged in the 'User'-section there. When using user trusted certificates, Android will force the user of the Android device to implement additional safety measures: the use of a PIN-code, a pattern-lock or a password to unlock the device are mandatory when user-supplied certificates are used.
Installing CAcert certificates as 'user trusted'-certificates is very easy. Installing new certificates as 'system trusted'-certificates requires more work (and requires root access), but it has the advantage of avoiding the Android lockscreen requirement.
From Android N onwards it gets a littler harder, see this extract from the Charles proxy website:
As of Android N, you need to add configuration to your app in order to have it trust the SSL certificates generated by Charles SSL Proxying. This means that you can only use SSL Proxying with apps that you control.
In order to configure your app to trust Charles, you need to add a Network Security Configuration File to your app. This file can override the system default, enabling your app to trust user installed CA certificates (e.g. the Charles Root Certificate). You can specify that this only applies in debug builds of your application, so that production builds use the default trust profile.
Add a file res/xml/network_security_config.xml to your app:
<network-security-config>
<debug-overrides>
<trust-anchors>
<!-- Trust user added CAs while debuggable only -->
<certificates src="user" />
</trust-anchors>
</debug-overrides>
</network-security-config>
Then add a reference to this file in your app's manifest, as follows:
<?xml version="1.0" encoding="utf-8"?>
<manifest>
<application android:networkSecurityConfig="@xml/network_security_config">
</application>
</manifest>
You can use XDocument.Parse
for this.
In your form are you passing in any other attributes, via mass assignment that don't belong to your user model, or any of the nested models?
If so, I believe the ActiveRecord::UnknownAttributeError is triggered in this instance.
Otherwise, I think you can just create your own controller, by generating something like this:
# app/controllers/registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
def new
super
end
def create
# add custom create logic here
end
def update
super
end
end
And then tell devise to use that controller instead of the default with:
# app/config/routes.rb
devise_for :users, :controllers => {:registrations => "registrations"}
Use the following code:
System.out.println("\f");
'\f' is an escape sequence which represents FormFeed. This is what I have used in my projects to clear the console. This is simpler than the other codes, I guess.
Got the same problem, found the following bug report in SQL Server 2012 If still relevant see conditions that cause the issue - there are some workarounds there as well (didn't try though). Failover or Restart Results in Reseed of Identity
For PHP, put this line of code before you start printing your XML:
while(ob_get_level()) ob_end_clean();

You need to convert the string to date using the to_date()
function
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31-Dec-2014','DD-MON-YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('31 Dec 2014','DD MON YYYY');
OR
SELECT * FROM OrderArchive
WHERE OrderDate <= to_date('2014-12-31','yyyy-MM-dd');
This will work only if OrderDate
is stored in Date format
. If it is Varchar
you should apply to_date()
func on that column also like
SELECT * FROM OrderArchive
WHERE to_date(OrderDate,'yyyy-Mm-dd') <= to_date('2014-12-31','yyyy-MM-dd');
Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.
You can check this by running in Windows PowerShell:
> Get-Service ssh-agent
And then check the output of status is not running.
Status Name DisplayName
------ ---- -----------
Stopped ssh-agent OpenSSH Authentication Agent
Then check that the service has been disabled by running
> Get-Service ssh-agent | Select StartType
StartType
---------
Disabled
I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:
> Get-Service -Name ssh-agent | Set-Service -StartupType Manual
Alternatively, you can set it through the GUI if you prefer.
I found that @tgamblin solution is not complete. It cannot handle with stackoverflow. I think because by default signal handler is called with the same stack and SIGSEGV is thrown twice. To protect you need register an independent stack for the signal handler.
You can check this with code below. By default the handler fails. With defined macro STACK_OVERFLOW it's all right.
#include <iostream>
#include <execinfo.h>
#include <signal.h>
#include <stdlib.h>
#include <unistd.h>
#include <string>
#include <cassert>
using namespace std;
//#define STACK_OVERFLOW
#ifdef STACK_OVERFLOW
static char stack_body[64*1024];
static stack_t sigseg_stack;
#endif
static struct sigaction sigseg_handler;
void handler(int sig) {
cerr << "sig seg fault handler" << endl;
const int asize = 10;
void *array[asize];
size_t size;
// get void*'s for all entries on the stack
size = backtrace(array, asize);
// print out all the frames to stderr
cerr << "stack trace: " << endl;
backtrace_symbols_fd(array, size, STDERR_FILENO);
cerr << "resend SIGSEGV to get core dump" << endl;
signal(sig, SIG_DFL);
kill(getpid(), sig);
}
void foo() {
foo();
}
int main(int argc, char **argv) {
#ifdef STACK_OVERFLOW
sigseg_stack.ss_sp = stack_body;
sigseg_stack.ss_flags = SS_ONSTACK;
sigseg_stack.ss_size = sizeof(stack_body);
assert(!sigaltstack(&sigseg_stack, nullptr));

"I want to hide some of the fields and do some complex validation."
I start with the built-in admin interface.
Build the ModelForm to show the desired fields.
Extend the Form with the validation rules within the form. Usually this is a clean
method.
Be sure this part works reasonably well.
Once this is done, you can move away from the built-in admin interface.
Then you can fool around with multiple, partially related forms on a single web page. This is a bunch of template stuff to present all the forms on a single page.
Then you have to write the view function to read and validated the various form things and do the various object saves().
"Is it a design issue if I break down and hand-code everything?" No, it's just a lot of time for not much benefit.
You can create a pre-filled form URL from within the Form Editor, as described in the documentation for Drive Forms. You'll end up with a URL like this, for example:
https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=Mike+Jones&entry.787184751=1975-05-09&entry.1381372492&entry.960923899
In this example, question 1, "Name", has an ID of 726721210
, while question 2, "Birthday" is 787184751
. Questions 3 and 4 are blank.
You could generate the pre-filled URL by adapting the one provided through the UI to be a template, like this:
function buildUrls() {
var template = "https://docs.google.com/forms/d/--form-id--/viewform?entry.726721210=##Name##&entry.787184751=##Birthday##&entry.1381372492&entry.960923899";
var ss = SpreadsheetApp.getActive().getSheetByName("Sheet1"); // Email, Name, Birthday
var data = ss.getDataRange().getValues();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
var url = template.replace('##Name##',escape(data[i][1]))
.replace('##Birthday##',data[i][2].yyyymmdd()); // see yyyymmdd below
Logger.log(url); // You could do something more useful here.
}
};
This is effective enough - you could email the pre-filled URL to each person, and they'd have some questions already filled in.
Instead of creating our template using brute force, we can piece it together programmatically. This will have the advantage that we can re-use the code without needing to remember to change the template.
Each question in a form is an item. For this example, let's assume the form has only 4 questions, as you've described them. Item [0]
is "Name", [1]
is "Birthday", and so on.
We can create a form response, which we won't submit - instead, we'll partially complete the form, only to get the pre-filled form URL. Since the Forms API understands the data types of each item, we can avoid manipulating the string format of dates and other types, which simplifies our code somewhat.
(EDIT: There's a more general version of this in How to prefill Google form checkboxes?)
/**
* Use Form API to generate pre-filled form URLs
*/
function betterBuildUrls() {
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName("Sheet1");
var data = ss.getDataRange().getValues(); // Data for pre-fill
var formUrl = ss.getFormUrl(); // Use form attached to sheet
var form = FormApp.openByUrl(formUrl);
var items = form.getItems();
// Skip headers, then build URLs for each row in Sheet1.
for (var i = 1; i < data.length; i++ ) {
// Create a form response object, and prefill it
var formResponse = form.createResponse();
// Prefill Name
var formItem = items[0].asTextItem();
var response = formItem.createResponse(data[i][1]);
formResponse.withItemResponse(response);
// Prefill Birthday
formItem = items[1].asDateItem();
response = formItem.createResponse(data[i][2]);
formResponse.withItemResponse(response);
// Get prefilled form URL
var url = formResponse.toPrefilledUrl();
Logger.log(url); // You could do something more useful here.
}
};
Any date item in the pre-filled form URL is expected to be in this format: yyyy-mm-dd
. This helper function extends the Date object with a new method to handle the conversion.
When reading dates from a spreadsheet, you'll end up with a javascript Date object, as long as the format of the data is recognizable as a date. (Your example is not recognizable, so instead of May 9th 1975
you could use 5/9/1975
.)
// From http://blog.justin.kelly.org.au/simple-javascript-function-to-format-the-date-as-yyyy-mm-dd/
Date.prototype.yyyymmdd = function() {
var yyyy = this.getFullYear().toString();
var mm = (this.getMonth()+1).toString(); // getMonth() is zero-based
var dd = this.getDate().toString();
return yyyy + '-' + (mm[1]?mm:"0"+mm[0]) + '-' + (dd[1]?dd:"0"+dd[0]);
};
This is a link to a great Case Study on the industry wide misunderstanding of controlling caches.
http://securityevaluators.com/knowledge/case_studies/caching/
In summary, according to this article, only Cache-Control: no-store
is recognized by Chrome, Firefox, and IE. IE recognizes other controls, but Chrome and Firefox do not.
You can print the PHP variable into your javascript while your page is created.
<script type="text/javascript">
var MyJSStringVar = "<?php Print($MyPHPStringVar); ?>";
var MyJSNumVar = <?php Print($MyPHPNumVar); ?>;
</script>
Of course this is for simple variables and not objects.
Use the adb tool that comes with the SDK.
adb push myDirectory /sdcard/targetDir
If you only specify /sdcard/
(with the trailing slash) as destination, then the CONTENTS of myDirectory will end up in the root of /sdcard.
You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:
In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file"
field, ostensibly for backward compatibility reasons.
So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.
You may have to perform a diff and put document.getElementById('name')
code inside a condition, in case your component is something like this:
// using the new hooks API
function Comp(props) {
const { isLoading, data } = props;
useEffect(() => {
if (data) {
var name = document.getElementById('name').value;
}
}, [data]) // this diff is necessary
if (isLoading) return <div>isLoading</div>
return (
<div id='name'>Comp</div>
);
}
If diff is not performed then, you will get null
.
return $picName = time().'.'.$request->file->extension();
The time()
function will make the image unique then the .$request->file->extension()
gets the image extension for you.
You can use this it works well with Laravel 6 and above.
Just to add my two cents to @dbr's answer, following is an example of how to implement this sentence from the official documentation he's cited:
"[...] to return a string that would yield an object with the same value when passed to eval(), [...]"
Given this class definition:
class Test(object):
def __init__(self, a, b):
self._a = a
self._b = b
def __str__(self):
return "An instance of class Test with state: a=%s b=%s" % (self._a, self._b)
def __repr__(self):
return 'Test("%s","%s")' % (self._a, self._b)
Now, is easy to serialize instance of Test
class:
x = Test('hello', 'world')
print 'Human readable: ', str(x)
print 'Object representation: ', repr(x)
print
y = eval(repr(x))
print 'Human readable: ', str(y)
print 'Object representation: ', repr(y)
print
So, running last piece of code, we'll get:
Human readable: An instance of class Test with state: a=hello b=world
Object representation: Test("hello","world")
Human readable: An instance of class Test with state: a=hello b=world
Object representation: Test("hello","world")
But, as I said in my last comment: more info is just here!
I think that this one is the simplest one and it accepts European and USA way of writing numbers e.g. USA 10,555.12 European 10.555,12 Also this one does not allow several commas or dots one after each other e.g. 10..22 or 10,.22 In addition to this numbers like .55 or ,55 would pass. This may be handy.

Arrays.asList(array)
Arrays
uses new ArrayList(array)
. But this is not the java.util.ArrayList
. It's very similar though. Note that this constructor takes the array and places it as the backing array of the list. So it is O(1)
.
In case you already have the list created, Collections.addAll(list, array)
, but that's less efficient.
Update: Thus your Collections.addAll(list, array)
becomes a good option. A wrapper of it is guava's Lists.newArrayList(array)
.
I wanted to see the hover state on my Bootstrap tooltips. Forcing the the :hover state in Chrome dev Tools did not create the required output, yet triggering the mouseenter event via console did the trick in Chrome. If jQuery exists on the page you can run:
$('.YOUR-TOOL-TIP-CLASS').trigger('mouseenter');
HttpClient
lives in the System.Net.Http
namespace.
You'll need to add:
using System.Net.Http;
And make sure you are referencing System.Net.Http.dll
in .NET 4.5.
The code posted doesn't appear to do anything with webClient
. Is there something wrong with the code that is actually compiling using HttpWebRequest
?
Update
To open the Add Reference dialog right-click on your project in Solution Explorer and select Add Reference.... It should look something like:
SELECT * FROM
(SELECT [UserID] FROM [User]) a
LEFT JOIN (SELECT [TailUser], [Weight] FROM [Edge] WHERE [HeadUser] = 5043) b
ON a.UserId = b.TailUser
Looks like the script executes before the DOM loads. Try loading the script asynchronously.
<script src="yourcode.js" async></script>
I wrote with parameters that are predefined
They are not "predefined" logically, somewhere inside your code. But as arguments of SP they have no default values and are required. To avoid passing those params explicitly you have to define default values in SP definition:
Alter Procedure [Test]
@StartDate AS varchar(6) = NULL,
@EndDate AS varchar(6) = NULL
AS
...
NULLs or empty strings or something more sensible - up to you. It does not matter since you are overwriting values of those arguments in the first lines of SP.
Now you can call it without passing any arguments e.g.
exec dbo.TEST
I think the problem is your script is executed before the target dom element is loaded in the dom... one reason could be that you have placed your script in the head of the page or in a script tag that is placed before the div element #main
. So when the script is executed it won't be able to find the target element thus the error.
One solution is to place your script in the load event handler like
window.onload = function () {
var main = new Vue({
el: '#main',
data: {
currentActivity: 'home'
}
});
}
Another syntax
window.addEventListener('load', function () {
//your script
})

$self has little to do with $, which is an alias for jQuery in this case. Some people prefer to put a dollar sign together with the variable to make a distinction between regular vars and jQuery objects.
example:
var self = 'some string';
var $self = 'another string';
These are declared as two different variables. It's like putting underscore before private variables.
A somewhat popular pattern is:
var foo = 'some string';
var $foo = $('.foo');
That way, you know $foo is a cached jQuery object later on in the code.
I found a simple explanation.

String a = "ABCD"
using this
a.toLowerCase();
all letters will convert to simple, "abcd"
using this
a.toUpperCase()
all letters will convert to Capital, "ABCD"
this conver first letter to capital:
a.substring(0,1).toUpperCase()
this conver other letter Simple
a.substring(1).toLowerCase();
we can get sum of these two
a.substring(0,1).toUpperCase() + a.substring(1).toLowerCase();
result = "Abcd"

int index = 0;
for (int i = 0; i < strlen(copy) + 1; i++) {
if (copy[i] != ' ')
{
res[index] = copy[i];
index++;
}
printf("End of iteration %d\n", i);
printf("Here is the initial line: %s\n", copy);
printf("Here is the resulting line: %s\n", res);

return res;

You can concatenate strings using strcat
. If you plan on concatenating numbers as strings, you must first use num2str
to convert the numbers to strings.
Also, strings can't be stored in a vector or matrix, so f
must be defined as a cell array, and must be indexed using {
and }
(instead of normal round brackets).
f = cell(N, 1);
for i=1:N
f{i} = strcat('f', num2str(i));
end

SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.

setx FOOBAR ""
just causes the value of FOOBAR to be a null string. (Although, it shows with the set
command with the "" so maybe double-quotes is the string.)
I used:
set FOOBAR=
and then FOOBAR was no longer listed in the set command. (Log-off was not required.)
Windows 7 32 bit, using the command prompt, non-administrator is what I used. (Not cmd or Windows + R, which might be different.)
BTW, I did not see the variable I created anywhere in the registry after I created it. I'm using RegEdit not as administrator.
One more solution, Using division. with twice traversal. Multiply all the elements and then start dividing it by each element.
In my opinion, utilizing Object.freeze
allows for a DRYer and more declarative style. My preferred pattern is:
./lib/constants.js
module.exports = Object.freeze({
MY_CONSTANT: 'some value',
ANOTHER_CONSTANT: 'another value'
});
./lib/some-module.js
var constants = require('./constants');
console.log(constants.MY_CONSTANT); // 'some value'
constants.MY_CONSTANT = 'some other value';
console.log(constants.MY_CONSTANT); // 'some value'
The following issue was fixed in v8 in Jan 2014 and is no longer relevant to most developers:
Be aware that both setting writable to false and using Object.freeze have a massive performance penalty in v8 - https://bugs.chromium.org/p/v8/issues/detail?id=1858 and http://jsperf.com/performance-frozen-object
I would say that it's preferable to use as few special characters as possible in REST URLs. One of the benefits of REST is that it makes the "interface" for a service easy to read. Camel case or Pascal case is probably good for the resource names (Users or users). I don't think there are really any hard standards around REST.
Also, I think Gandalf is right, it's usually cleaner in REST to not use query string parameters, but instead create paths that define which resources you want to deal with.
Another alternative is KMP (Knuth–Morris–Pratt).
The KMP algorithm searches for a length-m substring in a length-n string in worst-case O(n+m) time, compared to a worst-case of O(n·m) for the naive algorithm, so using KMP may be reasonable if you care about worst-case time complexity.
Here's a JavaScript implementation by Project Nayuki, taken from https://www.nayuki.io/res/knuth-morris-pratt-string-matching/kmp-string-matcher.js:
// Searches for the given pattern string in the given text string using the Knuth-Morris-Pratt string matching algorithm.
// If the pattern is found, this returns the index of the start of the earliest match in 'text'. Otherwise -1 is returned.
function kmpSearch(pattern, text) {_x000D_

var j = lsp[i - 1]; // Start by assuming we're extending the previous LSP_x000D_
while (j > 0 && pattern.charAt(i) != pattern.charAt(j))_x000D_

strip()
is a method for strings, you are calling it on a list
, hence the error.
>>> 'strip' in dir(str)
True
>>> 'strip' in dir(list)
False
To do what you want, just do
>>> l = ['Facebook;Google+;MySpace', 'Apple;Android']
>>> l1 = [elem.strip().split(';') for elem in l]
>>> print l1
[['Facebook', 'Google+', 'MySpace'], ['Apple', 'Android']]
Since, you want the elements to be in a single list (and not a list of lists), you have two options.
To do the first, follow the code:
>>> l1 = []
>>> for elem in l:
l1.extend(elem.strip().split(';'))
>>> l1
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']
To do the second, use itertools.chain
>>> l1 = [elem.strip().split(';') for elem in l]
>>> print l1
[['Facebook', 'Google+', 'MySpace'], ['Apple', 'Android']]
>>> from itertools import chain
>>> list(chain(*l1))
['Facebook', 'Google+', 'MySpace', 'Apple', 'Android']
You can do this by installing the task while running as administrator via the TaskSchedler library. I'm making the assumption here that .NET/C# is a suitable platform/language given your related questions.
This library gives you granular access to the Task Scheduler API, so you can adjust settings that you cannot otherwise set via the command line by calling schtasks
, such as the priority of the startup. Being a parental control application, you'll want it to have a startup priority of 0 (maximum), which schtasks
will create by default a priority of 7.
Below is a code example of installing a properly configured startup task to run the desired application as administrator indefinitely at logon. This code will install a task for the very process that it's running from.

jQuery < 1.8
May I suggest that you use $.ajax()
instead of $.post()
as it's much more customizable.
If you are calling $.post()
, e.g., like this:
$.post( url, data, success, dataType );
You could turn it into its $.ajax()
equivalent:
$.ajax({
type: 'POST',
url: url,
data: data,
success: success,
dataType: dataType,
async:false
});
Please note the async:false
at the end of the $.ajax()
parameter object.
Here you have a full detail of the $.ajax()
parameters: jQuery.ajax() – jQuery API Documentation.
jQuery >=1.8 "async:false" deprecation notice
jQuery >=1.8 won't block the UI during the http request, so we have to use a workaround to stop user interaction as long as the request is processed. For example:
$.ajax()
, and then remove it when the AJAX .done()
callback is called.Please have a look at this answer for an example.
Use a border-radius property of 50%.
So for example:
.example-div {
border-radius: 50%
}
If you end up with merge conflict and doesn't have anything to commit, but still a merge error is being displayed. After applying all the below mentioned commands,
git reset --hard HEAD
git pull --strategy=theirs remote_branch
git fetch origin
git reset --hard origin
Please remove
.git\index.lock
File [cut paste to some other location in case of recovery] and then enter any of below command depending on which version you want.
git reset --hard HEAD
git reset --hard origin
Hope that helps!!!

Quite simply:
You need to put the last()
indexing on the nodelist result, rather than as part of the selection criteria. Try:
(//element[@name='D'])[last()]
JQuery's :empty selector selects all elements on the page that are empty in the sense that they have no child elements, including text nodes, not all inputs that have no text in them.
Jquery: How to check if an input element has not been filled in.
Here's the code stolen from the above thread:
$('#apply-form input').blur(function() //whenever you click off an input element
{
if( !$(this).val() ) { //if it is blank.
alert('empty');
}
});
This works because an empty string in JavaScript is a 'falsy value', which basically means if you try to use it as a boolean value it will always evaluate to false
. If you want, you can change the conditional to $(this).val() === ''
for added clarity. :D
A simple work around(it worked for me) is use the IP address instead of localhost. This should be fine for your development tasks.
You can try finishAffinity()
, it closes all current activities and works on and above Android 4.1
It is pretty old thread but recently i had a similar issue. I was calling a downstream soap service, from a rest service, and I needed to return the xml response coming from the downstream server as is.
So, i ended up adding a SoapMessageContext handler to get the XML response. Then i injected the response xml into servlet context as an attribute.
public boolean handleMessage(SOAPMessageContext context) {
// Get xml response
try {
ServletContext servletContext =
((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getServletContext();
SOAPMessage msg = context.getMessage();
ByteArrayOutputStream out = new ByteArrayOutputStream();
msg.writeTo(out);
String strMsg = new String(out.toByteArray());
servletContext.setAttribute("responseXml", strMsg);
return true;
} catch (Exception e) {
return false;
}
}
Then I have retrieved the xml response string in the service layer.
ServletContext servletContext =
((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getServletContext();
String msg = (String) servletContext.getAttribute("responseXml");
Didn't have chance to test it yet but this approach must be thread safe since it is using the servlet context.
Well, I was looking to make my canvas fullscreen too, This is how i did it. I'll post the entire index.html since I am not a CSS expert yet : (basically just using position:fixed and width and height as 100% and top and left as 0% and i nested this CSS code for every tag. I also have min-height and min-width as 100%. When I tried it with a 1px border the border size was changing as I zoomed in and out but the canvas remained fullscreen.)

EDIT: add this to the canvas element:

_x000D_
</canvas>
_x000D_
add this to the javascript
canvas.width = window.screen.width;
canvas.height = window.screen.height;
I found this made the drawing a lot smoother than my original comment.
Thanks.
According to your sample,
<html>
<head>
<script src="jquery.js" type="text/javascript"></script>
<script src="abc.js" type="text/javascript">
</script>
<link rel="stylesheets" type="text/css" href="abc.css"></link>
<style>h2{font-wight:bold;}</style>
<script>
$(document).ready(function(){
$("#img").attr("src", "kkk.png");
});
</script>
</head>
<body>
<img id="img" src="abc.jpg" style="width:400px;height:300px;"/>
<script src="kkk.js" type="text/javascript"></script>
</body>
</html>
roughly the execution flow is about as follows:
<script src="jquery.js" ...
jquery.js
is downloaded and parsed<script src="abc.js" ...
abc.js
is downloaded, parsed and run<link href="abc.css" ...
abc.css
is downloaded and parsed<style>...</style>
<script>...</script>
<img src="abc.jpg" ...
abc.jpg
is downloaded and displayed<script src="kkk.js" ...
kkk.js
is downloaded, parsed and runNote that the download may be asynchronous and non-blocking due to behaviours of the browser. For example, in Firefox there is this setting which limits the number of simultaneous requests per domain.
Also depending on whether the component has already been cached or not, the component may not be requested again in a near-future request. If the component has been cached, the component will be loaded from the cache instead of the actual URL.
When the parsing is ended and document is ready and loaded, the events onload
is fired. Thus when onload
is fired, the $("#img").attr("src","kkk.png");
is run. So:
$("#img").attr("src", "kkk.png");
kkk.png
is downloaded and loads into #img
The $(document).ready()
event is actually the event fired when all page components are loaded and ready. Read more about it: http://docs.jquery.com/Tutorials:Introducing_$(document).ready()
By default, and from my current understanding, browser usually runs each page on 3 ways: HTML parser, Javascript/DOM, and CSS.
The HTML parser is responsible for parsing and interpreting the markup language and thus must be able to make calls to the other 2 components.
For example when the parser comes across this line:
<a href="#" onclick="alert('test');return false;" style="font-weight:bold">a hypertext link</a>
The parser will make 3 calls, two to Javascript and one to CSS. Firstly, the parser will create this element and register it in the DOM namespace, together with all the attributes related to this element. Secondly, the parser will call to bind the onclick event to this particular element. Lastly, it will make another call to the CSS thread to apply the CSS style to this particular element.
The execution is top down and single threaded. Javascript may look multi-threaded, but the fact is that Javascript is single threaded. This is why when loading external javascript file, the parsing of the main HTML page is suspended.
However, the CSS files can be download simultaneously because CSS rules are always being applied - meaning to say elements are always repainted with the freshest CSS rules defined - thus making it unblocking.
An element will only be available in the DOM after it has been parsed. Thus when working with a specific element, the script is always placed after, or within the window onload event.
Script like this will cause error (on jQuery):
<script type="text/javascript">/* <![CDATA[ */
alert($("#mydiv").html());
/* ]]> */</script>
<div id="mydiv">Hello World</div>
Because when the script is parsed, #mydiv
element is still not defined. Instead this would work:
<div id="mydiv">Hello World</div>
<script type="text/javascript">/* <![CDATA[ */
alert($("#mydiv").html());
/* ]]> */</script>
OR
<script type="text/javascript">/* <![CDATA[ */
$(window).ready(function(){
alert($("#mydiv").html());
});
/* ]]> */</script>
<div id="mydiv">Hello World</div>

In computer science, declarative programming is a programming paradigm that expresses the logic of a computation without describing its control flow.
From http://en.wikipedia.org/wiki/Declarative_programming
in a nutshell the declarative language is simpler because it lacks the complexity of control flow ( loops, if statements, etc. )
A good comparison is the ASP.Net 'code-behind' model. You have declarative '.ASPX' files and then the imperative 'ASPX.CS' code files. I often find that if I can do all I need in the declarative half of the script a lot more people can follow what's being done.
The easiest way to debug python - especially for programmers that are used to Visual Studio - is using PTVS (Python Tools for Visual Studio). The steps are simple:
If you want to debug Django using PTVS, you need to do the following:
I think you probably want to view the minification of each set of css as a separate task
task minifyBrandACss(type: com.eriwen.gradle.css.tasks.MinifyCssTask) {
source = "src/main/webapp/css/brandA/styles.css"
dest = "${buildDir}/brandA/styles.css"
}
etc etc
BTW executing your minify tasks in an action of the war task seems odd to me - wouldn't it make more sense to make them a dependency of the war task?
If you have one or more EditTexts inside of a recyclerview items, disable the autofocus of these, putting this configuration in the parent view of recyclerview:
android:focusable="true"
android:focusableInTouchMode="true"
I had this issue when I started another activity launched from a recyclerview item, when I came back and set an update of one field in one item with notifyItemChanged(position) the scroll of RV moves, and my conclusion was that, the autofocus of EditText Items, the code above solved my issue.
best.
You may try to put the right database name in connection url in the configuration file. As I had the same error while run the POJO class file and it has been solved by this.
I'm glad that worked out, so I guess you had to explicitly set 'auto' on IE6 in order for it to mimic other browsers!
I actually recently found another technique for scaling images, again designed for backgrounds. This technique has some interesting features:
The markup relies on a wrapper element:
<div id="wrap"><img src="test.png" /></div>
Given the above markup you then use these rules:
#wrap {
height: 100px;
width: 100px;
}
#wrap img {
min-height: 100%;
min-width: 100%;
}
If you then control the size of wrapper you get the interesting scale effects that I list above.
To be explicit, consider the following base state: A container that is 100x100 and an image that is 10x10. The result is a scaled image of 100x100.
So, in other words, the image is always at least as big as the container, but will scale beyond it to maintain it's aspect ratio.
This probably isn't useful for your site, and it doesn't work in IE6. But, it is useful to get a scaled background for your view port or container.
There are multiple ways how to present a timespan in the database.
time
This datatype is supported since SQL Server 2008 and is the prefered way to store a TimeSpan
. There is no mapping needed. It also works well with SQL code.
public TimeSpan ValidityPeriod { get; set; }
However, as stated in the original question, this datatype is limited to 24 hours.
datetimeoffset
The datetimeoffset
datatype maps directly to System.DateTimeOffset
. It's used to express the offset between a datetime
/datetime2
to UTC, but you can also use it for TimeSpan
.
However, since the datatype suggests a very specific semantic, so you should also consider other options.
datetime / datetime2
One approach might be to use the datetime
or datetime2
types. This is best in scenarios where you need to process the values in the database directly, ie. for views, stored procedures, or reports. The drawback is that you need to substract the value DateTime(1900,01,01,00,00,00)
from the date to get back the timespan in your business logic.
public DateTime ValidityPeriod { get; set; }
[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
get { return ValidityPeriod - DateTime(1900,01,01,00,00,00); }
set { ValidityPeriod = DateTime(1900,01,01,00,00,00) + value; }
}
bigint
Another approach might be to convert the TimeSpan into ticks and use the bigint
datatype. However, this approach has the drawback that it's cumbersome to use in SQL queries.
public long ValidityPeriod { get; set; }
[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
get { return TimeSpan.FromTicks(ValidityPeriod); }
set { ValidityPeriod = value.Ticks; }
}
varchar(N)
This is best for cases where the value should be readable by humans. You might also use this format in SQL queries by utilizing the CONVERT(datetime, ValidityPeriod)
function. Dependent on the required precision, you will need between 8 and 25 characters.
public string ValidityPeriod { get; set; }
[NotMapped]
public TimeSpan ValidityPeriodTimeSpan
{
get { return TimeSpan.Parse(ValidityPeriod); }
set { ValidityPeriod = value.ToString("HH:mm:ss"); }
}
Bonus: Period and Duration
Using a string, you can also store NodaTime datatypes, especially Duration
and Period
. The first is basically the same as a TimeSpan, while the later respects that some days and months are longer or shorter than others (ie. January has 31 days and February has 28 or 29; some days are longer or shorter because of daylight saving time). In such cases, using a TimeSpan is the wrong choice.
You can use this code to convert Periods:
using NodaTime;
using NodaTime.Serialization.JsonNet;
internal static class PeriodExtensions
{
public static Period ToPeriod(this string input)
{
var js = JsonSerializer.Create(new JsonSerializerSettings());
js.ConfigureForNodaTime(DateTimeZoneProviders.Tzdb);
var quoted = string.Concat(@"""", input, @"""");
return js.Deserialize<Period>(new JsonTextReader(new StringReader(quoted)));
}
}
And then use it like
public string ValidityPeriod { get; set; }
[NotMapped]
public Period ValidityPeriodPeriod
{
get => ValidityPeriod.ToPeriod();
set => ValidityPeriod = value.ToString();
}
I really like NodaTime
and it often saves me from tricky bugs and lots of headache. The drawback here is that you really can't use it in SQL queries and need to do calculations in-memory.
CLR User-Defined Type
You also have the option to use a custom datatype and support a custom TimeSpan
class directly. See CLR User-Defined Types for details.
The drawback here is that the datatype might not behave well with SQL Reports. Also, some versions of SQL Server (Azure, Linux, Data Warehouse) are not supported.
Value Conversions
Starting with EntityFramework Core 2.1, you have the option to use Value Conversions.
However, when using this, EF will not be able to convert many queries into SQL, causing queries to run in-memory; potentially transfering lots and lots of data to your application.
So at least for now, it might be better not to use it, and just map the query result with Automapper.
Prior answers focused on nominal data (e.g. unordered). If there is a reason to impose order for an ordinal variable, then one would use:
# Transform to category
df['zipcode_category'] = df['zipcode_category'].astype('category')
# Add ordered category
df['zipcode_ordered'] = df['zipcode_category']
# Setup the ordering
df.zipcode_ordered.cat.set_categories(
new_categories = [90211, 90210], ordered = True, inplace = True
)
# Output IDs
df['zipcode_ordered_id'] = df.zipcode_ordered.cat.codes
print(df)
# zipcode_category zipcode_ordered zipcode_ordered_id
# 90210 90210 1
# 90211 90211 0
More details on setting ordered categories can be found at the pandas website:
https://pandas.pydata.org/pandas-docs/stable/user_guide/categorical.html#sorting-and-order
Add repository annotation before your DAO Implementation Class. example:
@Repository
public class EmpDAOImpl extends BaseNamedParameterJdbcDaoSupportUAM
implements EmpDAO{
}

Hovercraft Full Of Eels' answer is very good, but i had to change it a bit in order to get it working on my program:
int y1 = (int) ((this.height - 2 * BORDER_GAP) - (values.get(i) * yScale - BORDER_GAP));
instead of
int y1 = (int) (scores.get(i) * yScale + BORDER_GAP);
because if i used his way the graphic would be upside down
(you'd see it if you used hardcoded values (e.g 1,3,5,7,9) instead of random values)
Thank you Felix Kling, but his answer need a little change:
var MySelect = React.createClass({
getInitialState: function() {
return {
value: 'select'
}
},
change: function(event){
this.setState({value: event.target.value});
},
render: function(){
return(
<div>
<select id="lang" onChange={this.change.bind(this)} value={this.state.value}>
<option value="select">Select</option>
<option value="Java">Java</option>
<option value="C++">C++</option>
</select>
<p></p>
<p>{this.state.value}</p>
</div>
);
}
});
React.render(<MySelect />, document.body);
Possibly unrelated, but if you want to start a new line after the current line, you can use o anywhere in the line.
An abstract class would be used when some common implementation was required. An interface would be if you just want to specify a contract that parts of the program have to conform too. By implementing an interface you are guaranteeing that you will implement certain methods. By extending an abstract class you are inheriting some of it's implementation. Therefore an interface is just an abstract class with no methods implemented (all are pure virtual).
Short answer is that you don't 'decrypt' the password (because it's not encrypted - it's hashed).
The long answer is that you shouldn't send the user their password by email, or any other way. If the user has forgotten their password, you should send them a password reset email, and allow them to change their password on your website.
Laravel has most of this functionality built in (see the Laravel documentation - I'm not going to replicate it all here. Also available for versions 4.2 and 5.0 of Laravel).
For further reading, check out this 'blogoverflow' post: Why passwords should be hashed.
Normally, the best-practice is to set the title on the UIViewController
. By doing this, the UINavigationItem
is also set. Generally, this is better than programmatically allocating and initializing a UINavigationBar
that's not linked to anything.
You miss out on some of the benefits and functionality that the UINavigationBar
was designed for. Here is a link to the documentation that may help you. It discusses the different properties you can set on the actual bar and on a UINavigationItem
.
Just keep in mind:
UINavigationController
's are your friends.
You can use another overload of the DropDownList
method. Pick the one you need and pass in
a object with your html attributes.
@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })
for example:
Connection conn = null; PreparedStatement sth = null; ResultSet rs =null; try { conn = delegate.getConnection(); sth = conn.prepareStatement(INSERT_SQL); sth.setString(1, pais.getNombre()); sth.executeUpdate(); rs=sth.getGeneratedKeys(); if(rs.next()){ Integer id = (Integer) rs.getInt(1); pais.setId(id); } }
with ,Statement.RETURN_GENERATED_KEYS);"
no found.
I realized that several answers have been provided but no real fix yet.
The reason, as mentioned above, is a "End of line" missing at the end of the CSV file.
While the real Fix should come from Microsoft, the walk around is to open the CSV file with a Text-editor and add a line at the end of the file (aka press return key). I use ATOM software as a text/code editor but virtually all basic text editor would do.
In the meanwhile, please report the bug to Microsoft.
Question: It seems to me that it is a office 2016 problem. Does anyone have the issue on a PC?
Here's a stored proc to do it:
CREATE OR REPLACE function timestamp_diff(a timestamp, b timestamp) return number is
begin
return extract (day from (a-b))*24*60*60 +
extract (hour from (a-b))*60*60+
extract (minute from (a-b))*60+
extract (second from (a-b));
end;

Up Vote if you also wanted to beat the crap out of the Oracle developer who negated to his job!
BECAUSE comparing timestamps for the first time should take everyone an hour or so...
In Doctrine 2.x you can't pass multiple order by using doctrine 'orderBy' or 'addOrderBy' as above examples. Because, it automatically adds the 'ASC' at the end of the last column name when you left the second parameter blank, such as in the 'orderBy' function.
For an example ->orderBy('a.fist_name ASC, a.last_name ASC')
will output SQL something like this 'ORDER BY first_name ASC, last_name ASC ASC'. So this is SQL syntax error. Simply because default of the orderBy or addOrderBy is 'ASC'.
To add multiple order by's you need to use 'add' function. And it will be like this.
->add('orderBy','first_name ASC, last_name ASC')
. This will give you the correctly formatted SQL.

The following was rejected as an edit to tvanfosson's answer. I was asked to contribute it as my own answer. I used his suggestion and finished the implementation of a ConfigurationManager
wrapper. In principle I simply filled out the ...
in tvanfosson's answer.
No. Extension methods require an instance of an object. You can however, write a static wrapper around the ConfigurationManager interface. If you implement the wrapper, you don't need an extension method since you can just add the method directly.
public static class ConfigurationManagerWrapper
{
public static NameValueCollection AppSettings
{
get { return ConfigurationManager.AppSettings; }
}
public static ConnectionStringSettingsCollection ConnectionStrings
{
get { return ConfigurationManager.ConnectionStrings; }
}
public static object GetSection(string sectionName)
{
return ConfigurationManager.GetSection(sectionName);
}
public static Configuration OpenExeConfiguration(string exePath)
{
return ConfigurationManager.OpenExeConfiguration(exePath);
}
public static Configuration OpenMachineConfiguration()
{
return ConfigurationManager.OpenMachineConfiguration();
}
public static Configuration OpenMappedExeConfiguration(ExeConfigurationFileMap fileMap, ConfigurationUserLevel userLevel)
{
return ConfigurationManager.OpenMappedExeConfiguration(fileMap, userLevel);
}
public static Configuration OpenMappedMachineConfiguration(ConfigurationFileMap fileMap)
{
return ConfigurationManager.OpenMappedMachineConfiguration(fileMap);
}
public static void RefreshSection(string sectionName)
{
ConfigurationManager.RefreshSection(sectionName);
}
}
If you use the static method and load the properties file from the classpath folder so you can use the below code :
//load a properties file from class path, inside static method
Properties prop = new Properties();
prop.load(Classname.class.getClassLoader().getResourceAsStream("foo.properties"));
In case there are any morons out there like me, I had this frustrating problem because I forgot a simple
new
keyword before instantiating a new object.
You can use the following command to revert all local changes:
svn st -q | awk '{print $2;}' | xargs svn revert
I don't think it is possible to do what the questioner asks which is to avoid dll hell by merging all the project files into one .exe.
The framework issue is a red herring. The problem that occurs is that when you have multiple projects depending on one library it is a PITA to keep the libraries in sync. Each time the library changes, all the .exes that depend on it and are not updated will die horribly.
Telling people to learn C as one response did is arrogant and ignorant.
This is what I did to integrate Identity with an existing database.
Create a sample MVC project with MVC template. This has all the code needed for Identity implementation - Startup.Auth.cs, IdentityConfig.cs, Account Controller code, Manage Controller, Models and related views.
Install the necessary nuget packages for Identity and OWIN. You will get an idea by seeing the references in the sample Project and the answer by @Sam
Copy all these code to your existing project. Please note don't forget to add the "DefaultConnection" connection string for Identity to map to your database. Please check the ApplicationDBContext class in IdentityModel.cs where you will find the reference to "DefaultConnection" connection string.
This is the SQL script I ran on my existing database to create necessary tables:

If you want to create a temp table after check exist table.You can use the following code
DROP TABLE IF EXISTS tempdb.dbo.#temptable
CREATE TABLE #temptable
(
SiteName NVARCHAR(50),
BillingMonth varchar(10),
Consumption INT,
)
After creating the temporary table, you can insert data into this table as a regular table:
INSERT INTO #temptable
SELECT COLUMN1,...
FROM
(...)
or
INSERT INTO #temptable
VALUES (value1, value2, value3, ...);
The SELECT statement is used to select data from a temp table.
SELECT * FROM #temptable
you can manually remove the temporary table by using the DROP TABLE statement:
DROP TABLE #temptable;

I am so used to just doing this with a Data Dictionary in Objective C. It was harder to get a similar result in Java for Android. I ended up creating a custom class, and then just doing a hashmap of my custom class.
public class Test1 {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addview);
//create the datastring
HashMap<Integer, myClass> hm = new HashMap<Integer, myClass>();
hm.put(1, new myClass("Car", "Small", 3000));
hm.put(2, new myClass("Truck", "Large", 4000));
hm.put(3, new myClass("Motorcycle", "Small", 1000));
//pull the datastring back for a specific item.
//also can edit the data using the set methods. this just shows getting it for display.
myClass test1 = hm.get(1);
String testitem = test1.getItem();
int testprice = test1.getPrice();
Log.i("Class Info Example",testitem+Integer.toString(testprice));
}
}
//custom class. You could make it public to use on several activities, or just include in the activity if using only here
class myClass{
private String item;
private String type;
private int price;
public myClass(String itm, String ty, int pr){
this.item = itm;
this.price = pr;
this.type = ty;
}
public String getItem() {
return item;
}
public void setItem(String item) {
this.item = item;
}
public String getType() {
return item;
}
public void setType(String type) {
this.type = type;
}
public int getPrice() {
return price;
}
public void setPrice(int price) {
this.price = price;
}
}
If you have a gridview containing more than one checkbox .... you should try this ....
Object[] o=new Object[6];
for (int i = 0; i < dgverlist.RowCount; i++)
{
for (int j = 2; j < dgverlist.ColumnCount; j++)
{
DataGridViewCheckBoxCell ch1 = new DataGridViewCheckBoxCell();
ch1 = (DataGridViewCheckBoxCell)dgverlist.Rows[i].Cells[j];
if (ch1.Value != null)
{
o[i] = ch1.OwningColumn.HeaderText.ToString();
MessageBox.Show(o[i].ToString());
}
}
}
You can make use of regex's quantifier feature since lookaround
may not be supported all the time.

Following Nick Craver's solution, setting the element's visibility allows it to get accurate dimensions. I've used this solution very very often. However, having to reset the styles manually, I've come to find this cumbersome, given that modifying the element's initial positioning/display in my css through development, I often forget to update the related javascript code. The following code doesn't reset the styles per say, but removes the inline styles added by javascript:
$("#myDiv")
.css({
position: 'absolute',
visibility: 'hidden',
display: 'block'
});
optionHeight = $("#myDiv").height();
optionWidth = $("#myDiv").width();
$("#myDiv").attr('style', '');
The only assumption here is that there can't be other inline styles or else they will be removed aswell. The benefit here, however, is that the element's styles are returned to what they were in the css stylesheet. As a consequence, you can write this up as a function where an element is passed through, and a height or width is returned.
Another issue I've found of setting the styles inline via js is that when dealing with transitions through css3, you become forced to adapt your style rules' weights to be stronger than an inline style, which can be frustrating sometimes.
I got the same issue on Android 9 because of the "http" and issue resolved by just adding android:usesCleartextTraffic="true" in AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<application
android:usesCleartextTraffic="true"

In windows 10, just exit out of current login and run this on command line
--> mysqladmin -u root password “newpassword”
where instead of root could be any user.
If you happened to run npm install
command on Windows, first make sure you open your command prompt with Administration Privileges. That's what solved the issue for me.
Big difference between an image and an iframe is the fact that an image keeps its aspect-ratio. You could combine an image and an iframe with will result in a responsive iframe. Hope this answerers your question.
Check this link for example : http://jsfiddle.net/Masau/7WRHM/
HTML:
<div class="wrapper">
<div class="h_iframe">
<!-- a transparent image is preferable -->
<img class="ratio" src="http://placehold.it/16x9"/>
<iframe src="http://www.youtube.com/embed/WsFWhL4Y84Y" frameborder="0" allowfullscreen></iframe>
</div>
<p>Please scale the "result" window to notice the effect.</p>
</div>
CSS:
html,body {height:100%;}
.wrapper {width:80%;height:100%;margin:0 auto;background:#CCC}
.h_iframe {position:relative;}
.h_iframe .ratio {display:block;width:100%;height:auto;}
.h_iframe iframe {position:absolute;top:0;left:0;width:100%; height:100%;}
note: This only works with a fixed aspect-ratio.

Nodemailer Module is the simplest way to send emails in node.js.
Try this sample example form: http://www.tutorialindustry.com/nodejs-mail-tutorial-using-nodemailer-module

The best way to do this is using WordPress class to authenticate users. Here is my solutions:
1. Include following WordPress PHP file:
include_once(dirname(dirname(dirname(__FILE__))) . DIRECTORY_SEPARATOR . "wp-includes" . DIRECTORY_SEPARATOR . "class-phpass.php");
2. Create an object of PasswordHash
class:
$wp_hasher = new PasswordHash(8, true);
3. call CheckPassword
function to authenticate user:
$check = $wp_hasher->CheckPassword($password, $row['user_pass']);
4. check $check
variable:
if($check) {
echo "password is correct";
} else {
echo "password is incorrect";
}
Please Note that: $password
is the un-hashed password in clear text whereas $row['user_pass']
is the hashed password that you need to fetch from the database.
I suppose it is better to use UTF-8 encoding in the string MD5.
public static string MD5(this string s)
{
using (var provider = System.Security.Cryptography.MD5.Create())
{
StringBuilder builder = new StringBuilder();
foreach (byte b in provider.ComputeHash(Encoding.UTF8.GetBytes(s)))
builder.Append(b.ToString("x2").ToLower());
return builder.ToString();
}
}
It is today possible to configure Safari to access local files.
- By default Safari doesn't allow access to local files.
- To enable this option: First you need to enable the develop menu.
- Click on the Develop menu Select Disable Local File Restrictions.

For me i was getting this error because i needed to put the arrays in paratheses. The error is a bit tricky in this case...
ie. concatenate((a, b))
is right
not concatenate(a, b)
hope that helps.
Argument is often used in the sense of actual argument vs. formal parameter.
The formal parameter is what is given in the function declaration/definition/prototype, while the actual argument is what is passed when calling the function — an instance of a formal parameter, if you will.
That being said, they are often used interchangeably, their exact use depending on different programming languages and their communities. For example, I have also heard actual parameter etc.
So here, x
and y
would be formal parameters:
int foo(int x, int y) {
...
}
Whereas here, in the function call, 5 and z
are the actual arguments:
foo(5, z);
Say, let we have column E
filled by formulas that returns string, like:
= " = " & D7
where D7
cell consist more complicated formula, that composes final desired result, say:
= 3.02 * 1024 * 1024 * 1024
And so in all huge qty of rows that are.
When rows are a little - it just enough to copy desired cells as values (by RMB)
to nearest column, say G
, and press F2 with following Enter in each of rows.
However, in case of huge qty of rows it's impossible ...
So, No VBA. No extra formulas. No F&R
No mistakes, no typo, but stupid mechanical actions instead only,
Like on a Ford conveyor. And in just a few seconds only:
D
G1
You can do it with:
UPDATE mytable SET Total = Pieces * Price;
You can cast it to a list, insert the item, then cast it back to a tuple.
a = ('Product', '500.00', '1200.00')
a = list(a)
a.insert(3, 'foobar')
a = tuple(a)
print a
>> ('Product', '500.00', '1200.00', 'foobar')
upper-case(string) and lower-case(string)
Another data.table
solution:
library(data.table)
setDT(group)[, head(.SD[order(-pt)], 1), by = .(Subject)]
Edit - Contained User (v12 and later)
As of Sql Azure 12, databases will be created as Contained Databases which will allow users to be created directly in your database, without the need for a server login via master.
CREATE USER [MyUser] WITH PASSWORD = 'Secret';
ALTER ROLE [db_datareader] ADD MEMBER [MyUser];
Note when connecting to the database when using a contained user that you must always specify the database in the connection string.
Traditional Server Login - Database User (Pre v 12)
Just to add to @Igorek's answer, you can do the following in Sql Server Management Studio:
Create the new Login on the server
In master
(via the Available databases
drop down in SSMS - this is because USE master
doesn't work in Azure):
create the login:
CREATE LOGIN username WITH password='password';
Create the new User in the database
Switch to the actual database (again via the available databases drop down, or a new connection)
CREATE USER username FROM LOGIN username;
(I've assumed that you want the user and logins to tie up as username
, but change if this isn't the case.)
Now add the user to the relevant security roles
EXEC sp_addrolemember N'db_owner', N'username'
GO
(Obviously an app user should have less privileges than dbo
.)
If you need to return a JSON object using a String, then the following should work:
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.http.ResponseEntity;
...
@RestController
@RequestMapping("/student")
public class StudentController {
@GetMapping
@RequestMapping("/")
public ResponseEntity<JsonNode> get() throws JsonProcessingException {
ObjectMapper mapper = new ObjectMapper();
JsonNode json = mapper.readTree("{\"id\": \"132\", \"name\": \"Alice\"}");
return ResponseEntity.ok(json);
}
...
}
That is for removing any space that is when you getting text from any text field but if you want to remove space between string you can use
xyz =[xyz.text stringByReplacingOccurrencesOfString:@" " withString:@""];
It will replace empty space with no space and empty field is taken care of by below method:
searchbar.text=[searchbar.text stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceCharacterSet]];
you can try this "KeyValuePair"
private KeyValuePair<int, int> GetNumbers()
{
return new KeyValuePair<int, int>(1, 2);
}
var numbers = GetNumbers();
Console.WriteLine("Output : {0}, {1}",numbers.Key, numbers.Value);
Output :
Output : 1, 2
Dim rnd As Random = New Random
rnd.Next(n)
A stateful server keeps state between connections. A stateless server does not.
So, when you send a request to a stateful server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between the two requests, that thing is "open" on the server.
When you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.
HTTP and NFS are stateless protocols. Each request stands on its own.
Sometimes cookies are used to add some state to a stateless protocol. In HTTP (web pages), the server sends you a cookie and then the browser holds the state, only to send it back to the server on a subsequent request.
SMB is a stateful protocol. A client can open a file on the server, and the server may deny other clients access to that file until the client closes it.
You can't (and shouldn't) block processing with a sleep function. However, you can use setTimeout
to kick off a function after a delay:
setTimeout(function(){alert("hi")}, 1000);
Depending on your needs, setInterval
might be useful, too.
You can use this Function if you have some variable in the SSIS.
Package pkg;
Microsoft.SqlServer.Dts.Runtime.Application app;
DTSExecResult pkgResults;
Variables vars;
app = new Microsoft.SqlServer.Dts.Runtime.Application();
pkg = app.LoadPackage(" Location of your SSIS package", null);
vars = pkg.Variables;
// your variables
vars["somevariable1"].Value = "yourvariable1";
vars["somevariable2"].Value = "yourvariable2";
pkgResults = pkg.Execute(null, vars, null, null, null);
if (pkgResults == DTSExecResult.Success)
{
Console.WriteLine("Package ran successfully");
}
else
{
Console.WriteLine("Package failed");
}
Another option is to use mouse, right click on "x reference". Context menu "CodeLens Options" will appear, saving all the navigation headache.
A great way of handling this is with regular expressions.
string modifiedString = Regex.Replace(originalString, @"(\r\n)|\n|\r", "<br/>");
This will replace any of the 3 legal types of newline with the html tag.
Works pretty well, in command line, all arguments are required, -W is for password
psql -h localhost -U user -W -d database_name -f path/to/file.sql
