GetDXVer Sample
Applications sometimes need to know which version of DirectX is currently available on the system. If an older version of DirectX is on the system, your application may need to scale itself to the capabilities of that version or install the most recent version.
The table lists the version of DirectX that shipped with each operating system:
| Operating System | DirectX Version |
|---|---|
| Windows 98 Gold | DirectX 5.2 |
| Windows 98 SE | DirectX 6.1a |
| Windows 2000 | DirectX 7.0 |
| Windows Millenium Edition | DirectX 7.1 |
| Windows XP | DirectX 8.1 |
DirectX 9.0 is supported on Windows XP.
The GetDXVer SDK sample has a function in it called GetDXVersion that returns the version of DirectX that is installed. As long as this integer is greater than or equal to your desired version number, your application will run normally.

Checking the Operating System Version
Use the Windows function GetVersionEx to check the operating system installed. This function returns an OSVERSIONINFOEX structure that contains a variety of information about the operating system.
