XWinVer - Simple class to get Windows OS version

• Download demo project - 35.8 KB

Introduction

There are many classes to get Windows version numbers, so why another one? Briefly, because none of them offered the simplicity and low overhead that I wanted, while giving me the information I needed. Instead of writing endless standalone functions (is it XP? is it SP2?), I decided to incorporate everything into a single class.

To keep the class overhead down to a minimum, I designed a new class as a singleton, with version data retrieved and stored only once per program.

XWinVer Functions

The CXWinVersion class includes functions to retrieve the OS version number both as an integer and a string value, as well as service pack.

Here are the functions available in CXWinVersion:

How To Use

To integrate XWinVer into your app, you first need to add XWinVer.h and XWinVer.cpp to your project. Next, include the header file XWinVer.h in each source module that you want to use CXWinVersion in. Now you can call CXWinVersion functions by just writing:

BOOL bXPSP2 = WinVersion.IsXPSP2();

Note that WinVersion is automatically instantiated when you include the header file XWinVer.h.
