// 0x0000 = No DirectX installed
|
|
// 0x0100 = DirectX version 1 installed
|
|
// 0x0200 = DirectX 2 installed

|
// 0x0300 = DirectX 3 installed
|
|
// 0x0500 = At least DirectX 5 installed.
|
|
// 0x0600 = At least DirectX 6 installed.
|
|
// 0x0601 = At least DirectX 6.1 installed.
|
|
// 0x0700 = At least DirectX 7 installed.
|
|
// 0x0800 = At least DirectX 8 installed.
|
|
//
|
|
// Please note that this code is intended as a general guideline. Your
|
|
// app will probably be able to simply query for functionality (via
|
|
// QueryInterface) for one or two components.
|
|
//
|
|
// Please also note:
|
|
// "if( dwDXVersion != 0x500 ) return FALSE;" is VERY BAD.
|
|
// "if( dwDXVersion < 0x500 ) return FALSE;" is MUCH BETTER.
|
|
// to ensure your app will run on future releases of DirectX.
