  Creating a PHP 5 Extension with Visual C++ 2005

This article describes the steps to create a custom PHP extension DLL for the Windows platform. The Zend API documentation that comes with PHP 5 on Windows (see php_manual_en.chm) does a good job explaining how to write extension methods, parse method parameters, and return values. But there is not currently a good step-by-step tutorial on how to get your first extension project up and running on Windows. The aim of this article is to fill that gap. Prerequisites Visual Studio 2005 You can...

  Launch Java process programmatically in Java

In some cases while working on some automation testcase, developers would like to launch Java process programmatically so that the tests can be ran without manual intervention. Java provides such methods to achieve this. ProcessBuilder can be used to build a Java process which can be launched when everything is ready. Basically it can take a list of parameters which are similar to the command line options/arguments.  For example, if you want to launch a Java process, you can do followi...

Sometimes, when dealing with Web application testing, verification routines related to SQL injection flaws discovery are restricted to the GET and POST variables as the unique inputs vectors ever. What about other HTTP header parameters? Aren’t they potential input vectors for SQL injection attacks? How can one test all these HTTP parameters and whic...
