Question: How do I execute an SQL script file in SQLPlus? Answer: To execute a script file in SQLPlus, type @ and then the file name. SQL > @{file} For example, if your file was called script.sql, you'd type the following command at the SQL prompt: SQL > @script.sql The above command assumes that the file is in the current directory. (ie: the current directory is usually the directory that you were located in before you launched SQLPlus.) If you need to execute a script file that is not in the current directory, you would type: SQL > @{path}{file} For example: SQL > @/oracle/scripts/script.sql This command would run a script file called script.sql that was located in the /oracle/scripts directory.

To change a password after installation: Start SQL*Plus: C:\> sqlplus /NOLOG Connect as SYSDBA : SQL> CONNECT / AS SYSDBA   Action SQL Statement Unlock a password ALTER USER username ACCOUNT UNLOCK; Lock a password ALTER USER username ACCOUNT LOCK; Change password of an unlocked account ALTER USER username IDENTIFIED BY password ; Change password of a locked account ALTER USER username IDENTIFIED BY password ACCOUNT UNLOCK;  

From your command prompt, type sqlplus "/ as sysdba" Once logged in as SYSDBA, you need to unlock the hr account SQL> alter user hr account unlock; SQL> grant connect, resource to hr;

To check file size you need PHP5 and Curl. It first try checking headers. But if file size is not specified in headers, it use cUrl to download the file and checks the size. File is saved in memory temporarily. <?php echo get_remote_size("http://www.google.com/"); function get_remote_size($url) {     $headers = get_headers($url, 1);     if (isset($headers['Content-Length'])) return $headers['Content-Length'];     if (isset($headers['Content-length'])) return $headers['Content-length'];     $c = curl_init();     curl_setopt_array($c, array(         CURLOPT_URL => $url,         CURLOPT_RETURNTRANSFER => true,         CURLOPT_HTTPHEADER => array('User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3'),         ));     curl_exec($c);     return curl_getinfo($c, CURLINFO_SIZE_DOWNLOAD); } ?>

Use Filter Validator  to validate url. filter_var($url, FILTER_VALIDATE_URL); Example using that, if (filter_var($url, FILTER_VALIDATE_URL) === FALSE) {     die('Not a valid URL'); }

Here I'm going to show how to add custom javascript to your backend(admin panel) and frontend of your wordpress website inside <head> tag.

Here is a simple method to check whether an app is on debug mode or not. This will be useful to check to enable Strict Mode or to disable Strict Mode. public static boolean isDebugMode(Context context) {               PackageManager pm = context.getPackageManager(); try {              ApplicationInfo info = pm.getApplicationInfo p (context.getPackageName(), 0);               return (info.flags & ApplicationInfo.FLAG_DEBUGGABLE) != 0; } catch (NameNotFoundException e) { }              return true; } And to enable Strict Mode, StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder() .detectAll() .penaltyLog() .penaltyDialog() .build()); The above code will detect all types of network and disk I/O. Very helpful for debugging.

By default post images not shown on home page by some themes. Showing images on articles in home page can be achieved by two ways. 1. You need to edit index.php of your theme. Remember you must edit currently activated theme. It is currently configured to only show a post excerpt. If you don’t supply an optional custom excerpt, WordPress will create one automatically by stripping out all formatting, markup and images from the first 55 words of your post. Replace the_excerpt() with the_content(). You can easily find the_excerpt() by clicking CTRL + F and typing the_excerpt() , find it replace. And save by clicking the update button. 2. Write a custom excerpt in the Excerpt field, under the post edit box. It can be as short, or as long, as you wish and can include images.

The following code will get the name of the page in php. It is sometimes useful to get name of the page. $uri = $_SERVER['REQUEST_URI']; $pieces = explode("/", $uri); if ($pieces[3] == "upload.php") { echo "Page name is upload.php"; } My Uri was "/tubesite/admin/upload.php". So when I run explode method, it returned array with three strings. First string $pieces[0] was an empty string. Second string was tubesite. And so on. You can check out explode method. It uses to form substrings by splitting it on boundaries formed by the string delimiter http://php.net/manual/en/function.explode.php
