Hello all I''ve got a strange problem with Direct Input (DX8) for Acquiring keyboard, in windowed mode The init methods works fine but when i went to Acquire, i''ve got a message error ''Acess Denied'' (SetCooperativeLevel to FOREGROUND | NONEXCLUSIVE) This problem occurs under MFC application (under a win 32 prog i''ve not this pb....) Someone has an idea ???? thanks for any help :-) ps: I''m sorry for my poor writing english ;-)

I set the "Debug output level" to max but i don''t understand the information (and it''s utility ;-)

DINPUT8: DIHid_BuildHidList(0)
DINPUT8: DIHid_CheckList(00000000)
DINPUT8: DIHid_CheckList(00000000) ->
DINPUT8: DIHid_BuildHidList(0) ->
DINPUT8: DIHid_GetDevicePath(00138948, 0012F474)
DINPUT8: DIHid_GetDevicePath(00138948, 0012F474) -> 00000001 OK
DINPUT8: DIHid_GetDevicePath(00138948, 0012F474)
DINPUT8: DIHid_GetDevicePath(00138948, 0012F474) -> 00000001 OK
DINPUT8: DIHid_BuildHidList(0)
DINPUT8: DIHid_BuildHidList(0) ->

"The access denied" error comes from HRESULT after call to
HRESULT hr = g_lpDIDevice->Acquire();

and it''s just says -> "Access is denied"

If you''re stepping through code, your app might not be in foreground and the acquire call might fail. Are you sure your application is the foreground and the active one when acquire is called?
