OSVERSIONINFO
The OSVERSIONINFO data structure contains operating system version information. The information
includes major and minor version numbers, a build number, a platform
identifier, and descriptive text about the operating system. This structure is used with
the GetVersionEx function.
typedef struct _OSVERSIONINFO{
DWORD dwOSVersionInfoSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
DWORD dwBuildNumber;
DWORD dwPlatformId;
TCHAR szCSDVersion[ 128 ];
} OSVERSIONINFO;
Members
dwOSVersionInfoSize
Specifies the size, in bytes, of this data structure. Set this member to sizeof(OSVERSIONINFO) before calling the GetVersionEx function.
dwMajorVersion

Windows NT version 3.51, the major version number is 3; and for Windows NT
version 4.0, the major version number is 4.
dwMinorVersion
Identifies the minor version number of the operating system. For example, for
Windows NT version 3.51, the minor version number is 51; and for Windows NT
version 4.0, the minor version number is 0.
dwBuildNumber
Windows NT: Identifies the build number of the operating system.
Windows 95: Identifies the build number of the operating system in the low-order word.
The high-order word contains the major and minor version numbers.
dwPlatformId
Identifies the operating system platform. This member can be one of the
following values:
Value
| Platform
| VER_PLATFORM_WIN32s
| Win32s on Windows 3.1.
| VER_PLATFORM_WIN32_WINDOWS
| Win32 on Windows 95.
| VER_PLATFORM_WIN32_NT
| Win32 on Windows NT.
|
szCSDVersion
Windows NT: Contains a null-terminated string, such as "Service Pack 3", that indicates
the latest Service Pack installed on the system. If no Service Pack has been
installed, the string is empty.
Windows 95: Contains a null-terminated string that provides arbitrary additional
information about the operating system.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
