I have this book Trick of Window Game Programming Guru, game lib. but i use DirectX SDK 8. the game library, T3DLIB1 works fine, but the T3DLIB2.H doesn''t work the error message is: error C2065: ''DirectInputCreate'' : undeclared identifier error C2065: ''DIDEVTYPE_JOYSTICK'' : undeclared identifier in fact, i already include all directX lib, header and source file for T3DLIB2, etc etc. I don''t know what''s wrong, is it because the sdk ? Thank you very much

It may be the SDK since the examples were designed for DX6. Also the DX8 SDK is pretty quirky. Try uninstalling DX8 SDK and then install the DX6 SDK and try compiling the examples.

Maybe we could change the game lib instead of replacing the sdk with the old one ?
do you have any solution about this ?

Thanks
