Applications use the methods of the IDirectInputEffect interface to manage effects of force-feedback devices.
The interface is obtained by using the IDirectInputDevice7::CreateEffect method.
The methods of the IDirectInputEffect interface can be organized into the following groups.
| Effect information | GetEffectGuid |
| GetEffectStatus | |
| GetParameters | |
| Effect manipulation | Download |
| Initialize | |
| SetParameters | |
| Start | |
| Stop | |
| Unload | |
| Miscellaneous | Escape |
The IDirectInputEffect interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:
| IUnknown | AddRef |
| QueryInterface | |
| Release |
