I'm having issues with getting the state of the mouse in managed DirectInput. I've scoured the forums, searched for tutorials, but so far I've come up empty. I'm using the Visual C# 2005 Express Beta.
mouse.SetCooperativeLevel(parent, CooperativeLevelFlags.NonExclusive | CooperativeLevelFlags.Foreground);
mouse.SetDataFormat(DeviceDataFormat.Mouse);
mouse.Acquire();

It throws an "ArgumentException" when I try to get the device state.
return mouse.GetDeviceState(typeof(MouseState));

I've tried different cooperative levels, and Ive tried different parameters to the call to GetDeviceState. All yield the same result. Does anyone know whats wrong? If you think I would be better off not using DirectInput for my mouse can you tell me why? thanks in advance!

Just use the CurrentMouseState property in Device. I believe that to use GetDeviceState you also have to use SetDataFormat so the device knows what kind of data it is gathering.

GetDeviceState takes 2 arguments

the size of the device state struct and the pointer to it.
