Basic knowledge

Q: How can I use functions from another class?

A: First condition: The function must be a "Shared" one. For example "Shared Function GetApp()". Second condition: in the target code, the class must be written beforehand (for example "Oni.GetApp" whereby "Oni" is the source class's name).

Code snippets

Common functions that are shared among VB.net projects should have their own class.

That way, the functions don't need be rewritten each time and it helps to keep the code more clear.

Class Oni

Functions in this class:

GetApp - returns app path (type string)

GetAE - returns AE home path (type string) (e.g. C:\Oni)

GetXSI - returns Mod Tool path (type string) (e.g. C:\Softimage\Softimage_Mod_Tool_7.5\Application\bin)

GetOniSplit - outputs an array with (0) as path (type string) and (1) as version (type string)

Imports System.IO ' for files and directories
Imports Microsoft.Win32 ' for registry keys
