Introduction: This tutorial is on how to run a function using it's reference name as a string in Visual Basic .NET. Built In: Luckily enough, the .NET framework has a built in function which allows an object, string function name, invoke type, and parameters to be called - this function is named 'CallByName'.

Introduction: This tutorial is on how to use Function Prototyping in C/C++. Function File: Here is a basic function file which, after running the 'int main' function, runs a custom function named 'calculate' which returns an integer and is output to the screen.

Introduction: This tutorial is on how to use encryption to transfer data securely, or at least more seucrely than plain text, from a Visual Basic application (or other source) to a PHP API. Why Cryptography? Cryptography should be used for all sensitive information being used in public release applications, or if the data is sent cross-networks.

Introduction This tutorial is on using MD5 encryption in PHP. Why MD5? MD5 is built in to PHP and is only a one way encryption. This means that even if someone was able to gain access to an encrypted md5 string, called an 'MD5 Hash', it is unlikely they would be able to convert the hash back in to the original plain text string. Decryption: Decryption in most cryptography languages essentially work by using the reverse algorithm to the encryption algorithm used by the cryptography method in question.
