VB 6.0 获取操作系统的名称及版本源码（模块）
发现博客园插入代码的列表里面没有VB一项，只有VB.NET。。。
前几天用VB写的一个获取网卡相关信息时用到的，收藏下，说不定以后还用得到!
其实最简单的方法就是读取环境变量里面的“OS”，即：Environ("OS")，但这样获取的值不准确，所以就有了下面这种方法：
Option Explicit
Public OSName As String '操作系统名称（简称），方便程序控制时根据操作系统取值
Public Type OSVERSIONINFO
dwOSVersionInfoSize As Long
dwMajorVersion As Long
dwMinorVersion As Long
dwBuildNumber As Long
dwPlatformId As Long
szCSDVersion As String * 128
wServicePackMajor As Integer
wServicePackMinor As Integer
wSuiteMask As Integer
wProductType As Byte
wReserved As Byte
End Type
Public Declare Function GetVersionEx Lib "kernel32" Alias "GetVersionExA" (lpVersionInformation As OSVERSIONINFO) As Long
' 获得 Windows 操作系统的名称，returnType决定返回的方式，值为0时，返回简称，否则返回全称
Public Function GetWindowsVersion(ByVal returnType As Integer) As String
Dim ver As OSVERSIONINFO, retLng As Long, os As String
ver.dwOSVersionInfoSize = Len(ver)
GetVersionEx ver
' retLng = GetVersionEx(ver)
' If retLng = 0 Then
' os = "Unknown System Version!"
' Exit Function
' End If
