Hi, i've recently purchased a XBox 360 controller for PC since i wanted to dabble with force feedback. Since the standard driver does NOT provide force feedback i installed the XBCD driver which works fine. I'm using XP Pro with SP2 installed. I've used the FFConst sample as a base from the October 2006 SDK which works nicely. To make sure i've got clean code i turned on debug DirectX in the control panel (debug to the max). Now everything works fine but it shows me this line: DINPUT8: unloaded before all objects released. (cRef:3) I've double checked and i am releasing everything that needs to be released. This same message also shows up with the original sample code. I've narrowed the offending code down by commenting lines, the problem seems to be the call: if( FAILED( hr = g_pDevice->SetProperty( DIPROP_AUTOCENTER, &dipdw.diph ) ) ) return hr; Now SetProperty shouldn't do anything in regard to reference counting AFAIK. There also is no UnSetProperty call (wouldn't make sense anyway). If i initialise, release completely and repeat this, the leak count goes up to 6 (it does add up). Anyone have any idea? Below is the full code i'm using, put into a simple MFC app. There would be more code after SetProperty but the error also pops up with this piece. Any obvious mistakes in there?
